Keyboard media keys un-lock the mouse cursor in most games

[headassbtw]

In windowed games (or even full-screen, with two monitors,) pressing media keys on a keyboard will unlock the mouse cursor.

I've had this happen across a variety of games, on a few different engines (Halo infinite, which is custom; Ultrakill which is unity; and Outriders, which is unreal; just to name a few)

Tested on proton 7.0-6, experimental, and other assorted versions i can't remember (it's been a persistent issue)

This does not happen on native linux games, Superhot has both and this issue only happens on the windows version

here's a demo video to show the issue:
