Issue description

I am using a option button to set my window mode. but I noticed every time I maximised my window using the maximised button on the application then changed the window mode to something else then back to windowed. it wouldn't be in windowed.(I cant really explain it well so just watch the video attached)

Steps to reproduce

In the Minimal reproduction project run the game. then in the top right there will be a Maximise button. click it then change the OptionButton in the center to either fullscreen or exclusive then change it back to windowed.

This is similar to my previous issue #79328 (the title had been changed but the description still shows my original issue which I think is related to this.)

Yesterday I faced the same issue with 4.2.1, decided to update to the latest 4.2.2 and it is still relevant

I am no longer able to reproduce this on 4.3 beta 2 and beta 3.

@alvinhochun Isn't this a duplicate of #93488? The descriptions look very similar.

Curiously no, I think some other change may have fixed the switch out of fullscreen. I don't have time to look at the code now.

Edit: My guess would be #88329
