Actual fullscreen in ParamountPlus, YouTube, etc. when using side-by-side windows
Is there a way to make the fullscreen button actually go fullscreen when I'm using 2 windows? I have 2 Google Chrome windows open side by side. If I try to fullscreen YouTube or Paramount Plus (haven't tested other apps yet), it only goes "full screen" on that half of the screen, which...isn't really "full" screen. Not sure why Apple designed it this way, I find this pretty annoying. Does anyone know a way to fix this issue?
