Thanks, Marshall. That's suppose to be a division slash, not "divides by". ;-)
The page source has unicode character 2215, which is suppose to be a division slash: http://www.fileformat.info/info/unicode/char/2215/index.htm So I'd suggest the browser is getting it wrong. But I think it can be worked around and just delegated to jsMath for a more humane treatment. Thanks for the report.
