    display: Unset grab_frame_action in meta_display_end_grab_op
    
    Otherwise, if the user had moved the windows around using a mouse,
    they can not be moved beyond the top edge of the primary monitor when
    the tray needs to be brought up, . This is because
    constrain_titlebar_visible looks at grab_frame_action and thinks that
    the movement is being caused by the user trying to move the windows up
    by grabbing the frame.
