Attachment of Instanced component does not work

Component hierarchy information is lost when modifying an Instance of a Blueprint that Inherits from a C++ Pawn. Specifically, when this instance's hierarchy is modified via the World Outliner Editor details panel.

1. Create a blueprint class MySMA with StaticMeshActor as the parent.
2. Inside of Blueprint Editor for MySMA add a Scene Component.
3. Compile & Save.
4. Drag an Instance of this Blueprint into the Level.
5. Select the Actor instance from the World Outliner, and from the details panel->Add Component-> Scene.
6. Attach this Scene1 Component so it is a child of the Scene(Inherited) component.
7. De-select off of the actor from the World Outliner(simply click another object)
8. Re-select the actor from the World Outliner and Observe the Component Hierarchy in the details panel.

Result: Scene1 is parented to the Root Component of the Actor, rather than a child of Scene Component.

Expected: Scene1 would successfully child to Scene Component.
