 - **Breaking:** On Web, the canvas element associated to a `Window` is no longer removed from the DOM when the `Window` is dropped.
 - On Web, `WindowEvent::Resized` is now emitted when `Window::set_inner_size` is called.
 - **Breaking:** `Fullscreen` enum now uses `Borderless(Option<MonitorHandle>)` instead of `Borderless(MonitorHandle)` to allow picking the current monitor.
