functions where this is the sole generic parameter.

This PR improves the performance of the `CopyButton` component by
tracking the copied state locally through a `CopyButtonState` struct
instead of making an OS call every time the component re-renders. Also
pushing a slight improvement here by resetting the state after two
seconds so as to make the check mark go away after you clicked to copy.
Release Notes:
- N/A
There were several places adding a copy icon button, so thought of
encapsulating the logic to copy a given string into the clipboard (and
other small details like swapping the icon and tooltip if copied) into a
component, making it easier to introduce this sort of functionality in
the future, with fewer lines of code.
All it takes (for the simplest case) is:
```rs
CopyButton::new(your_message)
```

Closes #ISSUE
Problem:
- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.
Fix:
- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

Release Notes:

immediately when focus moves to another panel or UI context.

- Fix missing font features in
`git_ui::blame_ui::GitBlameRenderer.render_blame_entry`
- Fix missing buffer font features in
`markdown_preview::markdown_renderer`
- Update the way that the markdown style is built for hover popovers so
that, for code blocks, the buffer font features are used.
- Introduce `gpui::Styled.font_features` to allow callers to also set
the font's features, similar to how `gpui::Styled.font_family` already
exists.
Relates to #44209
Release Notes:
- Fixed wrong font features in Blame UI, Hover Popover and Markdown
Preview
Closes#21324
Adds four new commands:
- `markdown::MoveUp`, `markdown::MoveDown` - these scroll up and down in
markdown preview mode, by no more than the height of a large headline.
- `markdown::MoveUpByItem`, and `markdown::MoveDownByItem` - these
scroll up and down by the height of the item at the top of the markdown
preview window. So headlines and large codeblocks, for instance, scroll
further than individual paragraph lines.
Also attempts to create sensible defaults:
`down` -> `markdown::ScrollDown`
`up` -> `markdown::ScrollUp`
`alt-down` -> `markdown::ScrollDownByItem`
`alt-up` -> `markdown::ScrollUpByItem`
And in Vim:
`ctrl-u` -> `markdown::ScrollPageUp`
`ctrl-d` -> `markdown::ScrollPageDown`
`ctrl-e` -> `markdown::ScrollDown`
`ctrl-y` -> `markdown::ScrollUp`
Release Notes:
- Added commands `markdown::ScrollUp`, `markdown::ScrollDown`,
`markdown::ScrollUpByItem`, and `markdown::ScrollDownByItem`
- Changed commands `markdown::MovePageUp` to `markdown::ScrollPageUp`
and `markdown::MovePageDown` to `markdown::ScrollPageDown`
Instead of allocating a one-element vec on the heap, we can just use an
array here (since `Editor::edit` accepts anything that implements
`IntoIterator`).
I haven't checked if there are more instances that can be simplified,
just accidentally stumbled upon this when working on something else in
the markdown preview crate.

Closes#39152
This PR fixes an issue where we would render Markdown tables full width
based on their container size. We now render tables based on their
content min size, meaning you are still allowed to make the table render
as it was before by making the columns `w_full`.
I had to change the `div()` to `v_flex().items_start()` because this
introduced a weird displaying behavior of the outside table border,
because the grid container was not shrinking due to It was always taking
up the full width of their container.

Release Notes:
- Markdown Preview: Markdown tables scale now based on their content
size
This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

- N/A *or* Added/Fixed/Improved ...
This PR adds support for `HTML` href elements. It also refactored the
way we stored the regions, this was done because otherwise I had to add
2 extra arguments to each `HTML` parser method. It's now also more
inline with how we have done it for the highlights.
**Small note**: the markdown parser only supports HTML href tags inside
a paragraph tag. So adding them as a root node will result in just
showing the inner text. This is a limitation of the markdown parser we
use itself.

Second take on https://github.com/zed-industries/zed/pull/37765.
This PR adds support for styling elements (**b**, **strong**, **em**,
**i**, **ins**, **del**), but also allow you to show the styling text
inline with the current text.
This is done by appending all the up-following text into one text chunk
and merge the highlights from both of them into the already existing
chunk. If there does not exist a text chunk, we will create one and the
next iteration we will use that one to store all the information on.

This PR allows you to define `align="right"` for example to change the
default alignment on **HTML** table columns. This PR also refactors
where we store the alignments in order to make it so you can define it
column based instead of only row based.
See that the `Revenue` column is left aligned instead of the default
`centered`.

Right now, we don't fill the empty column when the current row count is
less than the max row count. This PR fixes that by filling it with an
empty cell. So the table columns don't flow in the wrong direction, as
you can see inside the first screenshot.

Re-applies https://github.com/zed-industries/zed/pull/30840
This PR re-applies the initial
[PR](https://github.com/zed-industries/zed/pull/30840). As it was closed
because it was hard to land, because of the many conflicts. This PR
re-applies the changes for it.
In several cases we were creating multiple display_map
snapshots within the same root-level function call.
Creating a display_map snapshot is quite slow, and in some
cases we were creating the snapshot multiple times.
Release Notes:

We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

Re-adds: https://github.com/zed-industries/zed/pull/37264
This PR re-adds basic support for showing HTML images, without touching
the display mode for images.
The initial PR changed the `div().flex().flex_col()` to
`h_flex().flex_wrap()` but this broke the text wrapping in almost all
cases.
**Note**: This does not add support for showing the images inline,
because we haven't figured out how they correctly do this.
I'm working on adding the CSS `inline` display feature support to taffy
that hopefully allows us to correctly show images/other elements inline
without breaking the text wrapping.

Release Notes:
- Markdown: Added support for `HTML` block quotes
Follow-up: https://github.com/zed-industries/zed/pull/38590
**Note**: this PR contains changes from the [previous
PR](https://github.com/zed-industries/zed/pull/38590), when that PR gets
merged we should see the real changes.
This PR fixes 4 things in order to make:
1. Add html/markdown minifier to remove all the **\t** and **\n**
characters. This is needed as you cannot create new lines with markdown
by just adding an enter to the source file.
2. The event Event::HTML only contained a chunk of the real html for
multiline HTML code. I fixed this by storing the currently watched HTML
inside a buffer and at the end we parse it into the right elements.
Instead of trying to parse a chunck into multiple elements which would
always fail before.
3. Add support for html tables.
4. Fixed panic that occured when table does not have an header.
I also decided to keep the html minifier inside Zed, because making it a
dependency for just a few 100 lines seems to be an overkill. The
original crate had a few cve in their dependencies, so figured this
would be the best.
**Html table support**

Follow-up: #36700
This PR adds basic support for showing images inline inside a text.
As you can see inside the before screenshot, the image was displayed
right below the `Some inline text` text. This was because we didn't
consider the image to be inline with the text (paragraph). Now we do :)
All the test changes are making sure it is not more than 1 element
parsed, instead of only checking for the first parsed element. This
could work out bad when we return more than 1 result.

Release Notes:
- Markdown: Added support for inline HTML `img` tags inside paragraphs
This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.
