This issue does not occur when window.transparent is false

I need this feature working, as the application must use a custom window frame.
The apps appearance will need to be themed i.e. user-configurable, but to also support transitioning from Windows 10 to 11 and vice-versa.

I cannot use border radius on the window itself if the fullscreen functionality doesn't work when transparent windows are used.

Perhaps one could hack that feature up (our own fullscreen method and state) but it would be an ugly hack, and a lot of code would need to be changed for it to work properly again... especially on the frontend.
