[BUG] Issues with opengamepadui interacting with game exiting

[Aracnoss]

Describe the bug

Seems like two different bugs occuring depending on how you attempt to exit

1. Using the opengamepadui overlay hud to close the game, results in nothing happening.
2. Closing the game, via in-game elements, results in the game closing, but opengamepadui does not recognise the game has closed, resulting in opengamepadui remaining in it's overlay mode.

To Reproduce

Steps to reproduce the behavior:

1. Launch any* game
   a. Attempt to close via the overlay, not happens
   b. Close game, via in-game elements
   1. Game closes
   2. But opengamepadui remains in overlay mode

*Only test Steam games so far, but reproducible in any game I've tried.

Expected behavior

A clear and concise description of what you expected to happen.
