Invocations of methods named add_X or remove_X are not recorded

[stakx]

public interface IHaveMethodsNamedLikeEventAccessors
{
    void add_Something();
    void remove_Something();
}

[Fact] // fails
public void CanVerifyInvocationOfMethodNamedLikeEventAddAccessor()
{
    var mock = new Mock<IHaveMethodsNamedLikeEventAccessors>();
    mock.Object.add_Something();
    mock.Verify(m => m.add_Something(), Times.Once);
}

[Fact] // fails
public void CanVerifyInvocationOfMethodNamedLikeEventRemoveAccessor()
{
    var mock = new Mock<IHaveMethodsNamedLikeEventAccessors>();
    mock.Object.remove_Something();
    mock.Verify(m => m.remove_Something(), Times.Once);
}

Both verifications fail with Moq claiming that the methods were not called; for example:

Moq.MockException:
Expected invocation on the mock once, but was 0 times: m => m.add_Something()

Configured setups:
m => m.add_Something()
No invocations performed.
