Bug (Controller Input): Disconnecting a controller and connecting a new one not properly recognized

[iamsirenstorm]

Describe the bug

Connecting or starting a game with a controller works as intended, however, if you disconnect that controller and decide to plug in a separate controller, that new controller will not properly work with the game. This includes not being able to function while in-game and controller Panorama styles not being properly applied (though focus navigation still works).

To Reproduce

1. Start the game
2. Plug in any controller and load into any map
3. Interact with the game world, it should work as expected
4. Disconnect the controller and connect a new, separate controller
5. Attempt to interact again and observe that input is not being recognized
6. Optionally reconnect the previously used controller and observe that input is recognized as expected

Do the above steps while on the main menu and observe that controller specific styles are not being applied (InputController and associated styles to the main menu panel are missing), but you can still navigate around the menu.

Issue Map

Any map, also applies to Panorama UI

Expected Behavior

Controller input should always be recognized when swapping controllers around.

MainMenu panel (root UI panels) in Panorama should also always have the proper controller classes applied when any controller is connected, not just for the first one of the session.

Operating System

Windows 10 22H2 19045.6937

Adding to this:

Tested on Portal 2 and it faces something similar, but not exactly. Connecting a new controller functions as expected in Portal 2, where the input is properly recognized and you can interact with the game properly. From what I recall, I think Strata/P2:CE just uses Steam Input instead of Source's own input system.

However, in both games, if you hold down a direction and disconnect that controller, the move direction will not be released. So if you hold the stick left and disconnect the controller, you will constantly be moving to the left. Reconnecting the original controller will release this.
