Task Bar|Console: Adjusted 'taskbar' command behavior when task bar open

If the task bar is open but the command line is unfocused, 'taskbar'
will set focus to the command line rather than closing the task bar.
Only when the command line is focused and the task bar is open, the
command will close the task bar.
