    tiling: Do not restore maximized tile state when unmaximizing
    
    When a tiled window is maximized (e.g. by clicking the title bar
    button), unmaximizing the window restores the tiled state. While
    this is reasonable for side-by-side tiling, it is confusing for
    "maximize" tiled windows, as unmaximization has no visible effect.
    
    Change unmaximize to only restore the tiled state of side-by-side
    tiled windows.
