    shortcuts: Avoid centering the shortcuts window on the screen
    
    We should allow the window to place itself where it thinks it's most
    useful and for this we specify it's transient for the main window.
    
    Because the position was set to CENTER_ALWAYS, the window was being
    displayed and then moved to the center of the screen, thus flickering.
