GameObjects change Hierarchy order when undoing changing Transform type on multiple GameObjects

Scene Hierarchy

-

Steps to reproduce:

  1. Create a new Unity project using a 3D Universal Template
  2. In the Hierarchy, create an empty GameObject
  3. Duplicate the created GameObject 3-4 times
  4. Select the middle two (e.g. "GameObject (2)" and "GameObject (3)") GameObjects in Hierarchy
  5. In the Inspector, add the "Rect Transform" Component to the selected GameObjects
  6. Press Ctrl+S to save the Scene
  7. Click Ctrl+Z to undo
  8. Observe the Hierarchy

Actual results: The selected GameObjects change their order in the Hierarchy

Expected results: GameObjects should remain in the same order as before (e.g. GameObject (1), GameObject (2), GameObject (3), etc.)
