Original mocked type not included after downcasting and Get

[pjquirk]

Consider this code:

using Moq;

public class Program
{
    public interface B { }
    public interface A : B { } 
    	
    public static void Main() 
    {
        Mock<A> a = new Mock<A>();
	// a.As<A>();  // workaround
        B b = a.Object;
        Mock<B> mockb = Mock.Get(b);
        Mock<A> c = mockb.As<A>();  // throws
    }
}

The line to assign c fails with an InvalidOperationException because it doesn't think the mock that wraps B implements A. Note that uncommenting the 'workaround' line fixes the problem.

The workaround makes me think this is a bug rather than intended behavior.

Hi @pjquirk, and thanks for reporting this.

To be honest, I'm not sure whether to classify this as a "bug", or as an "enhancement". But I'm happy to go along with your suggestion that this is a bug.
