IsEqualTo Fails for Non-Generic IEnumerable

[MrKWatkins]

I'd expect the following to pass:

[Test]
public async Task Test()
{
    IEnumerable value = new List<int> { 1, 2, 3 };
    await Assert.That(value).IsEqualTo(value);
}

But instead I get the error:

Expected value to be equal to System.Collections.Generic.List`1[System.Int32]

but found System.Linq.Enumerable+CastICollectionIterator`1[System.Object]

at Assert.That(value).IsEqualTo(value)

IsSameReferenceAs also fails.

That's probably because my last request, which forces it to behave as a IEnumerable<object>:
