## Context
Since https://github.com/zed-industries/zed/pull/52232/, there have been
a lot of problems related to panels randomly hiding and showing
themselves. However, the code in that PR is pretty innocuous. It
shouldn't be having that kind of effect. However, it turns out there's a
bug in how GPUI subscriptions work that caused there to be orphaned
observe callbacks firing spuriously. The core sequence is captured in
`test_unsubscribe_during_callback_with_insert`, essentially you have to
have two observers on the same item (`SettingsStore`, in this case),
that both drop themselves. If the first observer _adds_ a callback onto
the _same item_, then the second observer will never successfully drop
itself.
While in there, I also fixed an unrelated bug that @maxbrunsfeld noticed
where if you have two callbacks on the same item, and an earlier
callback drops a later one, then the second callback will spuriously
fire.
I also added a few extra smoke tests to the subscription code, and a
test capturing the observed bug at the workspace level.
