Undoing reparenting of a modelNode causes modelNodes to go out of sync with actual model somehow

• Create new project
• Delete all nodes except scene root
• Add red rectangle called "red" and a blue rectangle called "blue" (order is important, red should be above blue)
• Reparent red to blue
• Undo (ctrl-z)

-> The reparenting is undone, but the red rectangle now shows id "blue" in navigator and the blue rectangle has no id, so it just shows "Rectangle" as name. Code view shows correct ids. If you now change the id of either rectangle, it actually changes the id of the other one, so their internal nodes are somehow mixed up.
