[UI] [Wayland only] Action search not working

[mara004]

Commit Hash
About window says 15556c6, but actually it should be 72d5b4a
(which is because I pulled from git and only ran make without cmake)

Platform
KDE Neon User 5.21.5 (Linux)
Graphics Platform: Wayland

Summary
The action search seems to be broken. Keyboard input is simply not getting recognised (not even ESC for closing the search), hence no actions will be shown.

Additional Information / Output
My Qt input module (QT_IM_MODULE) is compose.

I'm guessing this is exclusive to Wayland. @elsandosgrande might be able to confirm. I can confirm it works fine on X11.

Hmm, maybe it's even an issue with my build? Need to verify that.

[mara004]

I just rebuilt and the issue is still present, so it likely is another Wayland-only problem indeed. However, it used to work, so this bug may have been introduced recently.

@itsmattkc I can confirm it does work properly if the app is launched as XWayland client. You're right it's only a problem for native Wayland.

Merging all Wayland issues into #1630.
