Undo action is not registered when undoing GameObjects list order in the Hierarchy window



How to reproduce:

1. Create a new Unity project
2. In the Hierarchy window create two GameObjects (command+shift+N)
3. Select both GameObjects and drag them over between Directional Light and Main Camera in Hierarchy window
4. Undo changes (command+Z)
5. Redo changes (command+shift+Z)
6. Observe the Hierarchy window

Expected result: Both GameObjects position in the Hierarchy window can be redone
Actual result: Only one GameObject returns to its previous order in the Hierarchy window

    Sounds very similar what I'm seeing currently with 2022.1.20, where undo and redo consistently refuse to restore the correct sibling order (parenting goes correctly).
