- On Wayland, fix deadlock when calling to `set_inner_size` from a callback.
- On macOS, add `hide__other_applications` to `EventLoopWindowTarget` via existing `EventLoopWindowTargetExtMacOS` trait. `hide_other_applications` will hide other applications by calling `-[NSApplication hideOtherApplications: nil]`.
- On MacOS, Fixed fullscreen and dialog support for `run_return`.
