When closing the keyboard via other means than the right button in the bottom drawer the shell doesn't realize it's closed and won't open it again
This is mostly noticeable in QMLKonsole which has it's own button to show and hide the keyboard. If I press that to close the keyboard, the button in the bottom right doesn't realize the keyboard is closed and will still show the down arrow icon rather than the close icon. Pressing it does nothing.
This is only fixable by pressing the keyboard icon in QMLKonsole again to bring the keyboard back up, then closing it via the icon in the shell
