We are seeing the timestamp comparison fail in an unexpected way, e.g. https://zed-dev.sentry.io/issues/7293482758/events/c7f7eab3f8f2463f879d4889a80d623e, where it seems like `text::Anchor::is_max` should be returning true but it apparently isn't. Add some more information when this panic happens to understand what's going on. Release Notes: - N/A Co-authored-by: Piotr Osiewicz <24362066+osiewicz@users.noreply.github.com>
