Closes#31805
This is an issue with Linux currently that `window.focus` is `None` upon
startup in both X11 and Wayland. Specifically, the order in which
[this](8d05a3d389/crates/gpui/src/window.rs (L3116))
and
[this](8d05a3d389/crates/gpui/src/app.rs (L956))
are executed varies between Linux and macOS. That is, one tries to
remove (blur) focus from a window, while other checks window focus to
put that focus id to a frame. In macOS, blur happens afterwards setting
focus on a frame, but in Linux, the inverse of it happens, leading to
`window.focus` to `None`.
For the time being, we handle all visible buttons to take care of this
**focus can be `None`** case, and make it work anyway. But, we should
look at the deeper issue mentioned above with GPUI. Created new issue to
track that https://github.com/zed-industries/zed/issues/34591.
Release Notes:
- Fixed an issue where button clicks wouldn’t work on startup until
clicked on the center pane on Linux.
