    appDisplay: Ensure icons always are at the correct position
    
    When redisplaying, we currently only remove and add icons, but
    never adjust the position of already added icons. If the icon
    position changed, it wouldn't be reflected on the icon grid.
    
    Make sure to move already added icons.
