Please describe your issue in as much detail as possible:

Entering or leaving docked mode mid-game does not correctly detect the new controller.

When entering docked mode, this can be fixed sometimes by changing the controller order. Sometimes this doesn't work and

When exiting docked mode, the controller order dissapears (as there is only the steam deck controller now I suppose) and it is impossible to change the controller order to fix the issue. Only solution is to restart the game entirely.

Steps for reproducing this issue:

1. Dock the SD into official valve dock
2. Start game using Xbox wired controller
3. Undock the SD
4. Attempt to continue playing, notice that controls no longer register, however a mouse will still work and SteamOS still reads inputs.

Possibly related to ValveSoftware/steam-for-linux#9150.

This is happening even after that fix, so probably not the exact cause.
