Hello and thanks for the report!
That's a hell of a catch, and I can't believe no one has pointed this out sooner. I certainly didn't catch it so kudos to you!
I will file this one ASAP! Once again this is a pretty "Doh!" moment for me as a QA tester, so thank you for your help in pointing this one out! :-)
