Expected behaviour
Konsole should simply close when using Alt+F4.
Actual behaviour
Alt+F4 only closes Konsole if no command is running. e.g. this hotkey fails to close the terminal if another subshell is running in konsole.
I fixed this by simply clicking on `Enable all "Do Not Ask Again" notifications" option in Konsole's settings.
Alt+F4then simply close Konsole when used subsequently?
