Multiple Signal Receivers Components on a single GameObject can cause a Crash when signals target the playable director

Timeline

-

1. Import attached package
2. Open signalCrash scene
- The timeline has a signal at the end of the timeline
- The Cube contains two separate signal receivers which make calls to the playableDirector.
3. Enter Playmode
4. Wait for the timeline to play.

When the timeline ends, the editor will often crash.
