Non-terminating while loop when creating a new BP Actor and quickly switching between components.

It is possible for the while loop in UnrealEditor-SubobjectDataInterface.dll!USubobjectDataSubsystem::GetActorRootHandle(const FSubobjectDataHandle & StartingHandle) Line 815  to not terminate when quickly switching between components while in the Actor Blueprint Editor. See video posted here for repro [Link Removed]

Create a new BP Actor and add some components. Quickly change between those components in the editor. Eventually the editor will lock and end up in an infinite loop.
