A couple of small tweaks. (#4569)

* Stop ignoring the safe area with the suggestions view.

They weren't visible on iPad (hidden behind the sidebar) and I can't find any instance when they're shown where the safe area comes into play.

* Make sure the room list deselects the cell when dismissed a room.

* Use the backports pattern in more places.

* Fix the annoying header on macOS.

* Silence some warnings

* Fix compound CI branch name.
