"Clear Parent Socket" on Actor Component causes crash

Engine version 5.1.1
Add-ons: none
engine source: Epic Games Launcher (other engine source, or version could not be confirmed)
Steps to reproduce:
-Create New Blueprint with Parent Actor “BP_MyActor”, and save it.
-Create New Blueprint with Parent Actor Component “BP_MyActorComponent”, and save it
-in “BP_MyActor” add “BP_MyActorComponent” to Hierarchy, Compile, and Save it
-in “BP_MyActor” select the “BP_MyActorComponent” in the Hierarchy
-in Details Sockets->Parent Socket, “X” button [Clear the Parent Socket] is accessible.
-click “X” button [Clear the Parent Socket]
-editor will now crash

expected behavior: button inaccessible if nothing to remove, a warning, not crashing…

Issue resolved as late as Engine version 5.2.1 (could have been 5.2.0 but unknown.
