What doesn't work:
When using a Ctrl + [key] standard shortcuts in the plasma wayland session, nothing happens. E.g. copy/paste file in Dolphin using Ctrl+C/Ctrl+V doesn't copy the file. Also Ctrl+A in kwrite for an unsaved file doesn't trigger the save-as dialog.

What works:
- Other standard shortcuts, like refreshing the view in Dolphin [F5].
- Ctrl + [key] standard shortcuts in X-windows like KMail or Firefox.
- Detection of event by libinput:
=== (example ctrl+v)
 event0         KEYBOARD_KEY      +5.71s        KEY_LEFTCTRL (29) pressed
 event0         KEYBOARD_KEY      +6.63s        KEY_V (47) pressed
 event0         KEYBOARD_KEY      +6.85s        KEY_V (47) released
 event0         KEYBOARD_KEY      +8.91s        KEY_LEFTCTRL (29) released
