You have asked in the wrong forum. This forum is for questions and discussions about the TechNet Wiki.
You have already asked your question in what appears to be the best forum. Another good place to ask would be here:

There is also a link on the page to a UserVoice for Sway, which would be a good place to report a suspected bug.
