Editor Performance issue : Loading/unloading multiple Levels / Level Instances triggers each time a call to FActorFolders::RebuildFolderListForWorld

Description

Revisit how FActorFolders are updated when loading/unloading Levels (level instances).
The code should maintain the folder list instead of rebuilding everything.

Steps to Reproduce

Steps to Reproduce

  • Place thousands of Level Instances on a streaming level
  • Hide/unhide the streaming level
  • Notice how long it takes to load the levels although they don't necessarily contain too much actual data
