Unable to add new keyboard shortcuts: only 'cancel' available
Reproduced with git commit 1d0c21be.
When I'm trying to add a new keyboard shortcut, the dialog accepts keystrokes and displays them but provides no way to confirm it:
If I keep pressing keys, the 'shortcut' updates but the dialog doesn't close. If I press 'cancel', the shortcut is obviously not created. If I press enter, 'shortcut' is updated to enter and 'cancel' is activated immediately afterwards.
