Controller disconnecting on Android device while button is pressed causes the game to continue having that input pressed

Description

NOTE: I am not certain that this is a RetroArch issue. If the issue is relevant to the core instead of the overall app, please feel free to close this issue.

While a button was held down on a controller, the controller disconnected. The actual disconnection is not a problem as I believe this was the controller's fault and it reconnected after a few seconds. However, the button continued to be held down in-game and the game refused to acknowledge anything other than that existing button press. After minimising and restoring the app, entering and existing the menu and generally messing around with the screen and controller, the game began to accept other inputs but still
continued to behave as though the previously-held button was still held down. Again, after some time (perhaps a minute in-game), the game stopped behaving as though the button was held down and I was able to continue normal gameplay again.
I was playing Shantae (Game Boy Color) at the time, using the VBA-M core set to emulate Game Boy Advance.

Expected behavior

While a controller button was being held down, the game would detect no input after the disconnection of the controller.

Actual behavior

When the controller disconnected while a controller button was being held down, the game continued to behave as though the button was held down for a while.

Steps to reproduce the bug

1. Connect controller
2. Hold button down on controller
3. Get controller to disconnect while holding down a button?

Bisect Results

I have only experienced this once on 1.19.1

• RetroArch: 1.19.1 Nightly (2024-06-13)

Environment information

• OS: Android 14 (Samsung Galaxy S23)

No source file or test is named. Start by reproducing the Android controller-disconnect sequence described in the issue, then trace the input handling path for disconnect events; done means the active button state is cleared and the game accepts subsequent input immediately.
