@milesbigbluedoor, Hi, I am not able to reproduce in the current master branch, maybe this has been fixed? Can you provide your .md file, so that I can test your .md in master branch as well?

@richardtks I just messed around with my preferences and discovered this is an issue caused by the Sanitization option under Interface being set to Allow dangerous html tags. Can you try setting your Sanitization setting to the same and see if that breaks it?
