Equivalency of multidimensional arrays with zero size width

[quinmars]

Following code throws an exception (System.IndexOutOfRangeException : Index was outside the bounds of the array.):

[Fact]
public void Test()
{
    Array a = new long[1,0] { { } };
    Array b = new long[1,0] { { } };

    a
        .Should().BeEquivalentTo(b);
}

I'd expect a to be equivalent to b.

I'm using version 5.9.0 of FluentAssertions.

Defintiely a bug.
