Reproduced on these devices:

Could not test with these devices due to not being able to connect the controller:

Notes:
- On the device which reproduced the issue, none of the controller's buttons worked (ZL, ZR, buttonSouth, buttonNorth, etc.)
- The original report said that the Nintendo Switch Pro controller is recognized as "AndroidGamepadWithDpadAxes" in the Input Debugger, while it was recognized as "AndroidJoystick" during testing
- The controller seemed to not work throughout the Android system at all, even though it did show up as connected and the particular device should support the controller
