We are having an issue with red "invalid-markup" boxes showing next to equations created using the built-in Canvas math equation tool.  These boxes only appear when using Firefox.  They do not appear in Chrome.  I have included screenshots of the issue, along with a screenshot of the HTML for this page.  I'm not sure what might be causing the issue.  Does it relate to something about how Firefox picks up the HTML for the math equations?

 @mdonovan1 , greetings! This is an interesting/strange issue. My recommendation is to contact Canvas Support to see if they are aware of the issue and to see if they can help. To do this, click on the Help link in Canvas and "Report a Problem." Please let us know what support has to say!
