 // This verifies WindowObservers are removed when a window is destroyed after
 // the Shell is destroyed. This scenario (aura::Windows being deleted after the
 // Shell) occurs if someone is holding a reference to an unparented Window, as
 // is the case with a RenderWidgetHostViewAura that isn't on screen. As long as
 // everything is ok, we won't crash. If there is a bug, window's destructor will
 // notify some deleted object (say VideoDetector or ActivationController) and
 // this will crash.
