Undo is not working when Renaming a Missing Prefab in the Hierarchy

Scene Management

-

1. Open the attached project named Case_1165052
2. Rename the missing MissingPrefab gameObject
3. Press CTRL+Z to Undo the name change

Expected result: Editor changes back the missing prefab's name
Actual result: Editor does not change the missing prefab's name. Also, the Scene becomes not Dirty even though an object has a different name

Reproducible with: 2017.4.30f1, 2018.4.3f1, 2019.1.9f1, 2019.2.0b9, 2019.3.0a9

    Resolution Note (fix version 2021.2):

    Fixed in - Unity 2021.2.0a11. The renaming of the missing prefabs is now disabled to prevent such issues. The rename option in the Context menu is now greyed out and double-clicking to rename throws an appropriate warning
