[HL2, Portal] GamepadUI pause menu phantom button press
This bug is reproducible 100% of the time while playing the native Linux build of Half Life 2 (or Episodes One/Two) or Portal 1 on the Steam Deck OLED with the default Steam Input control setup.
- Pause any of the aforementioned games with the menu/start button (to the left of the Y button)
- Select "Resume Game" with the A button
- Pause the game again with the menu/start button
- The game will automatically click onto Resume Game without the user pressing anything.
Note: it only happens when you select Resume Game with the A button. If you instead just press menu/start to close the pause menu, it will not cause the bug.
