Reverting a child object added to a Prefab deletes the child object from the Scene completely

Steps to reproduce:

1. Create any primitive (e.g. a Cube)
2. Drag the primitive to the Project Window to create a prefab
3. Create any other primitive (e.g. a Sphere)
4. Drag this primitive under the initial prefab to make it a child of the prefab
5. Select the initial prefab
6. Click on Overrides in the Inspector
7. 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
