[BUG] [Steam Deck] Cannot use controller and mouse together

[revanmj]

Describe the bug

As title says, once controller kicks in, you cannot use touchpad as a mouse (app does not react to it) despite setting it as one in SteamOS settings.

To Reproduce

1. Use controller layout with touchpad set as a mouse
2. Launch the app in Game Mode and start a game in it
3. It reacts to all controller inputs, but not to touchpad as a mouse input

Screenshots

No response

Version

2.1.3

Is this a fresh install of the app or an update from a past version?

Fresh

Did this issue appear right away upon installation/updating, or spontaneously?

Yes

Additional context

This is a bit annoying as for example you cannot close any popups Steam sometimes shows (for example about syncing error) that block starting the game and do not react to controller input.

Also, I did make sure that flatpak permissions for udev were granted.
