    keyboard: Reset height before requesting preferred height
    
    If we don't set the height property to -1 before requesting the
    preferred height, get_preferred_height() will just return us the fixed
    height that has been set before. We don't want this behavior here, so
    set the height to -1 before calling get_preferred_height().
    
    This fixes a resizing issue where the keyboard is sized incorrectly
    after switching the monitor into portrait mode and back.
