    overview: Avoid repositioning windows while returning to desktop
    
    When returning to the desktop from overview we always show the
    workspaceDisplay, given that is which have the windows clones to allow
    animations.
    The problem becomes when previous that we were at some other
    page, like Search or AppDisplay. The problem is that when showing the
    workspaceDisplay the windows are repositioned. That's wanted except
    when returning from overview, since that causes unwanted animations
    of the windows.
    To avoid that just not reposition the windows if leaving the overview.
