 // . The transient parent destroys any transient children when it is
 //   destroyed. This means a transient child is destroyed if either its parent
 //   or transient parent is destroyed.
 // . If a transient child and its transient parent share the same parent, then
 //   transient children are always ordered above the transient parent.
 // Transient windows are typically used for popups and menus.
 // TODO(sky): when we nuke TransientWindowClient rename this to
 // TransientWindowController.
