Editor freezes on selection of Blueprint Components

Editor freezes and stops responding on selection of Blueprint Components; Requiring the editor to be forced closed.

Repro Rate: 4/4

Tested this in //UE4/Release-4.27 @ CL#18319896 and the issue did occur there, it is not a regression.

1. Create a new blank BP project
2. Create a new Blueprint based on Actor
3. Add in four RectLight components and close the Blueprint
4. In the scene, add ~100 of these Blueprints.
5. Open the Blueprint with the RectLights, ensuring it's popped out from the editor so it's overlaying the scene.
6. Click through the Rect Lights one at a time.

Results: Editor Freezes after clicking on the components
Expected: Editor does not freeze and allows selection of the components.
