Fix#4451. The reporter's analysis is correct - the method has a bug. The solution is relatively easy. Nevertheless, proving that the fix works as desired is tricky. The submitter's Reflection test is good, but it would be better to find one within Excel. My additional tests are contrived, for reasons explained in the test member. So, I will leave this as a work in progress while I search for something better. If that search doesn't succeed, I will nevertheless merge this in about a month.
