OnTransformChildrenChanged doesn't get called in the Edit mode when dragging a Prefab from the Project window to the Hierarchy
How to reproduce:
1. Open the user's attached project
2. Open Scenes > SampleScene
3. From the Assets folder drag the 'Prefab' under the Parent object in the Hierarchy
4. Observe the Console
Expected result: 'Children changed! Prefab' appears in the Console
Actual result: The Console is empty

Not reproducible with: 2018.4.33f1
Notes:
