Editor crash when deleting a outline folder with subfolders and using context menu

Editor crash when deleting a outline folder with subfolders and using context menu

Description

A user has reported that when using the Scene Outliner in a large map that has many actors and nested folders in the Outliner, deleting a folder that has subfolders from the Scene Outliner with Delete key and at the same time right clicking that folder and hovering "Move To" in the context menu causes a crash.

Because folder deletion is instant and usually doesn't let you right click the item that you've just removed, this is likely an issue with complex maps only where slow performance of the delete action and/or editor UI refresh allow this scenario.

Steps to Reproduce

Provided by user:

  1. Open/Create a map with a lot of actors/folders(repro'ed on a map with 60k actors and hundreds of folders).
  2. Select one of the folders in the map.
  3. Right-click and create a subfolder, giving it a unique name( e.g. “abc1” )
  4. Right-click on the newly created folder and add a subfolder to it, giving it a unique name (e.g. “abc2”).
  5. Select the first subfolder you created.
  6. Use the “del” keyboard key to delete the folder. At the same time attempt to right click on the same folder and move the cursor to the “Move To” option in the sub-menu.
  7. Observe crash or repeat steps.
