Some Nodes in a Group can paint outside the clipping bounds

JavaFX 8.0-b90
(also JavaFX 2.2.21)

Nodes in the scenegraph will occassionally render outside of the area if the clip shape. A simple Rectangle is being used as a clip shape. I have a complex set of nodes in an AnchorPane. The clipping rectangle and the anchor point of the Group that is contained in the AnchorPane are adjusted simultaneously to scroll view of the Group. Some nodes that are deep within the node hierarchy of the Group will paint outside the AnchorPane.
