<p dir="auto">the syntax checker and mobile viewer have had compounding issues for me as a work through this tutorial in firefox.<br>
this is how this challenge loaded without my changing any of the text. The mobile view shows duplicated content which doesn't match the code<br>

<p dir="auto">Challenge <a href="http://www.freecodecamp.com/challenges/waypoint-create-a-bootstrap-headline" rel="nofollow">http://www.freecodecamp.com/challenges/waypoint-create-a-bootstrap-headline</a> has an issue. Please describe how to reproduce it, and include links to screenshots if possible.</p>
<p dir="auto">The sidebar (for clarity, I am referring to the area shown in the attached screenshot) seems to scroll with a mind of its own. I have noticed this on several of the Bootstrap challenges (I did not see this on any HTML challenges). This is usually just a minor nuisance, but can be quite annoying when you are trying to hit a button to go to the next challenge (or submit a bug!).</p>
<p dir="auto">In addition, the cursor seems to be off in the text editor portion. Typing and selecting text can be off by one line.</p>
