Description

An ensure (ensure( !PersistentLayout->PrimaryArea.IsValid() )[Image Removed] is firing in FTabManager::PersistLayout() sometimes when docking/undocking quickly.

Steps to Reproduce
  • Selecting an actor in the level
  • Repeatedly docking and undock the details and/or the outliner tabs (doing so rapidly seems to make the repro more reliable)
  • Observe the triggered ensure
