[Drupal] Class Name Filtering

[Walker, Robert T.]

We're running D7 and Panopoly and the HTML editor is stripping out css classes that begin with hyphen (ex: class="button -alt" produces class="button"). I've found that allowed class names are filtered in the Rules for Class Names section of /admin/config/content/formats/panopoly_html_text but when I add -*, it says it's an invalid expression. However, W3C says a single hyphen is allowed at the beginning of a class.

What's the best way to get hyphen classes to be in output?

Thanks,
Rob
