Unable to open On-Screen Keyboard while in Game Menu in Fullscreen Mode

[Lesniak17]

As the title says - unable to open On-Screen Keyboard while in Game Menu in Fullscreen Mode.
For example when creating a new world trying to change its name, or when trying to add a server to the list.
"STEAM + X" does nothing, either in Desktop or Gamepad control mode.

Device: SteamDeck
OS: SteamOS
Game Launcher: Prism
Mod Version: 2.5.1+1.21.fabric
