Steps to reproduce:
# Create any primitive (e.g. a Cube)
# Drag the primitive to the Project Window to create a prefab
# Create any other primitive (e.g. a Sphere)
# Drag this primitive under the initial prefab to make it a child of the prefab
# Select the initial prefab
# Click on Overrides in the Inspector
# Click Revert All

Expected result: the parent object isn't completely deleted, but is reverted to its original location in the Hierarchy

Actual result: the object disappears from the Scene completely

Reproducible with: 2023.1.0a12, 2022.2.0a1, 2022.1.0a1. 2019.4.20f1
