    Description

      JDK-8090322 added an internal treeShowing property that tracks whether a node is both treeVisible and showing (i.e., attached to a scene that is attached to a window that is showing).

      This causes a listener to be added to the Scene for each node in the scene, making it expensive to add and remove nodes from the scene graph. A performance optimization would be to compute this only for the subset of UI controls need to know whether a node is treeShowing.
