Duplicate prefab gets created when undo is pressed after applying override to nested prefabs. Refer the attached video.

Steps to reproduce:
1) Create new project
2) Create two empty gameObjects A and B> Create prefabs of both of them.
3) In hierarchy, add B as a child of A.
4) Select both the prefabs and in the override window > Apply all
5) Press Ctrl+z or Edit > Undo

Actual result : Additional duplicate prefab B is created.
Expected result: The changes are undone and no duplicate prefabs are created
