Steps to reproduce:
1. Open the attached user project "MulticastDelegate.zip"
2. Make sure to change the path of the automatic memory snapshot ("Assets/Test.cs" line 83)
3. Build and run the Standalone Windows Player
4. Open Memory Profiler, select the taken snapshot and "Unity Objects"
5. Scroll down to the “MonoBehaviour“ script and select the “GameObject“ nested in it
6. On the right side under References expand “SceneRoot GameObject“-> “MonoBehaviour“
7. Finally expand the two “Test.HandPoser“ and observe the nested “System.Action<System.Boolean>“ events

Expected results: Two C# events are seen
Actual results: Three C# events are seen (See attached Repro.png)
