Duplicating actor blueprint messes up component hierarchy

Duplicating an actor Blueprint (via ALT+drag, copy paste, or CTRL+W) will result in the copy losing all Hierarchy structure from the original.

1. Create an Actor Blueprint and add 2 scene components to the root
2. Drag that Blueprint into the scene and add some static mesh components to each to the scene components
3. Clone the actor in the scene and notice that the copy will not have any of the Hierarchy set from the original.

Expected result would be that the copied actor would keep the same Hierarchy as the original.
