Tommy Chow f07fe621bc fix stale fullscreen button icon and system UI mode not reacting to settings
Wrap fullScreenButton in Observer so icon/tooltip update immediately
when toggling fullscreen. Move system UI immersive mode sync into the
videoChat Observer so it reacts to landscapeForceVerticalChat changes.
