💡 Can you add an additional test for an event with an initializer? I don't think it's going to change anything but it seems like a test gap:

public static event EventHandler StaticEvent = delegate { };
public event EventHandler InstanceEvent = delegate { };

@vweijsters You feeling confident about this one now? 😄

Should be OK now, but I'm not betting anything on it 😉
