This is needed because when the user drags a new scene component over the existing one, the old one should be deleted but is still marked as the SceneRoot (and cannot be deleted because we have to update the instances of the archetypes)

Correctly sort non-scene components to the bottom of the component tree.
This is some logic that was missed during the SCS editor refactor and is known to work already.

The SubobjectDataSubsystem is how users can manipulate a given object within Blueprints or Python scripting. Given a Uobject instance in a level or a UBlueprint asset, you can use GatherSubobjectData to get get an array of handles that you can use to manipulate that subobject.
This is what the new SubobjectEditor (Previously the SCS editor) will be using instead of having all its logic within slate code.
