Keyboard shortcuts do not work when TacentView opened from specific apps

[faerot]

When I open the file from messenger (qTox), the opened TacentView does not react to key presses, but when same file opened from file manager (Dolphin), keyboard works.
I am using latest version (1.0.46) installed from snap on Kubuntu 24.04.

Could not repo. Tried on Kubuntu 25.10 with qTox version 1.17.6-2-debian (installed from deb file) and Tacent View Snap 1.0.47. The viewer responded to keyboard input when opening an image sent from one qTox test user to another.
