- Returning `IntoElement` because it's more universal than `Element` and
allows us to easily return components.
- Using `impl IntoElement` in `RenderOnce` for consistency, which
requires `Component` to allocate an `AnyElement`. We use a bump
allocated arena anyway for these, and my benchmark doesn't show an
impact.

In this histogram, frames-0 is this PR, frames-1 is main.

This PR polishes off the channel buttons such that they behave as
expected.
The absolutely-positioned button container will now no longer take up
space—and thus obscure the channel name—when there are no notifications
and the channel entry is not hovered.
Release Notes:
- N/A
This PR is another pass at improving the positioning of channel buttons.
I had to employ some dirty hacks to get it to work, but I think it is
~mostly there.
Release Notes:
- N/A
This PR absolutely positions the channel buttons on top of the channels.
This prevents the buttons from getting pushed off the edge of the panel
when the channel names are long.
Still needs some fine-tuning, but gets us closer to where we want to be.
Release Notes:
- N/A
This makes it a bit more approachable to implement.
This required converting the state of Component to AnyElement, which
costs an allocation. I'm hoping this will be ok performance-wise now
that AnyElements use bump allocation, but I need to benchmark still.
This PR adjusts the sizes of the current call controls in the title bar
to be smaller.
This matches the size of the other title bar items that are always
present.
Release Notes:
- N/A
This addresses a bug where popover menus in the titlebar were rendered
only after a 2nd click. The first click was creating the View which the
second one then rendered.
In addition to this, `PopoverMenu::menu` function argument can now
return an `Option<View<T>>` instead of `View<T>` as the creation of the
menu can fail (as it might in case of git popover).
Release Notes:
- N/A
This PR increases the indent step size for the collab panel.
This gives the channel list a clearer hierarchy for nested channels, as
well as help align the disclosures with the parent channel's icon.
Release Notes:
- N/A
This PR adjusts the sizing of the labels in the buttons in the title bar
to use the small label size.
This should bring them more in line with how things looked in Zed1.
Release Notes:
- N/A
* Ensure that views' on_release callbacks are always called (even if
their window is gone), by passing them a `AppContext`, not a
`WindowContext`.
* Fix leaked handles to `CollabPanel`, `NotificationPanel`, and
`ChatPanel` caused by captures in a `ListState` render callback.
This fixes two issues we were seeing with following:
* inability to rejoin a remote project after you closed it
* following not working if a window had previously been closed
* allow confirming all items via the keyboard
* allow deploying the channel context menu via the keyboard
* add missing selected styling for list items
