    window: Reset tile-mode on maximization
    
    We used to restore side-by-side tiling when unmaximizing, so we
    kept the tile-mode during maximization. Since commit 10d53fc7d
    there's no longer a good reason to do so, and it can result in
    tile previews being shown erroneously on window drag operations
    without motion (double-click on titlebar), so reset the tile
    mode in maximize().
