[Steam Deck] Gamemode: Returning to the quick menu is prevented after opening the keyboard when a game is running in the Steam version

Description

As mentioned in the title, after you open up the (Steam) virtual keyboard in the quick menu while a game is running (be it through the search option or otherwise), when resuming the currently running game, you'll be unable to access the quick menu or any sort of hotkeys, forcing you to quick out of RetroArch through the Steam quick menu.
This only happens with the Steam version in Gamemode, as it will use the built-in virtual keyboard while in Desktop mode, and neither the Flatpak nor the Appimage versions use the Steam keyboard in Gamemode at all.
Another note is that is only happens when the Steam virtual keyboard is opened in situations where the built-in virtual keyboard would've opened normally (I.E. opening the Steam virtual keyboard through the Steam button + X combo doesn't trigger the bug).

Version/Commit

• RetroArch: 1.16.0.3

Environment information

• OS: Steam OS 3.5.7.

Reproduce the issue in the Steam version on Steam Deck Game Mode with a game running, comparing the Steam virtual keyboard opened from the quick menu with the Steam button + X path. Verify whether resuming leaves the quick menu and hotkeys unusable; done means returning to the quick menu and using hotkeys works normally after the affected keyboard flow.
