Adding an actor with a default property track immediately after opening a sequence will crash the editor

If an actor has default property tracks set up in the Project Settings, adding that actor to a level sequence through C++ will crash the editor. This seems to stem from the creation of the default property track triggering a key to be added to the sequence, which triggers another key to be added to the sequence over and over.

1. Download attached project
2. Extract and launch it
3. Run the CrashReproWidget editor utility widget
4. Click the button on the widget 

RESULT

The editor will crash.

Fatal error!
