How to reproduce:
1. Open the attached “IN-150915_Repro” project
2. Open scene “RenamedValueScene“
3. Make sure that the RenamedValue GameObject “New Value“ is set to 23
4. Make sure that the RenamedValue Prefab “New Value“ is set to 17
5. Run Repro → ValidateAndRevertAfterRename
Actual result:PrefabUtility.RevertPropertyOverride does not revert it; the instance remains at 23, the stored modification path remains oldValue even after saving and reopening the scene
Expected result: The override preserved through [FormerlySerializedAs("oldValue")] is recognized on newValue; RevertPropertyOverride restores the Prefab Asset value of 17.
