#UE-3724 - LIVE: BP: If a comment box is created inside of another larger comment box the smaller box is no longer editable #Branch UE4 #Proj UnrealEd, GraphEditor #info this issue came about after recent changes to slate resulted in OnHitTest no longer being called by design. This changelist seeks to eliminate the requirement for this by correctly sorting the comments in arrangedchildren. codereview Nick.Atamas [CL 2377331 by Ben Cosh in Main branch]
