set_title in with_document_title_changed_handler does nothing on Wayland

[ColonelThirtyTwo]

Describe the bug
Setting a window's title using Window.set_title inside of a callback registered in with_document_title_changed_handler does nothing.

Steps To Reproduce
Replace examples/simple.rs with the following code and run it. Observe the window title, and the message in stderr confirming that the callback is called with a valid title and window.

      ..
    } = event
    {
      *control_flow = ControlFlow::Exit;
    }
  });
}

Expected behavior
The window's title changes to match the document title.

Additional context

Forcing xwayland by running via env WAYLAND_DISPLAY=asdf cargo run --example simple makes the example work.
