Ampersands not displayed correctly

[leesei]

In http://docs.nodejitsu.com/articles/javascript-conventions/what-are-truthy-and-falsy-values,
The ampersands are displayed as HTML entities:

var myvalue = first && second;

The preview of the contend.md is correct though.
https://github.com/nodejitsu/docs/edit/master/pages/articles/javascript-conventions/what-are-truthy-and-falsy-values/content.md

Is this a bug of the syntax highlighter? Extra classes are added to the string &.

I noticed this as well while browsing the Cryptography page. As stated, the preview of the document in GitHub is correct, but the rendering in docs displays the ampersands as HTML entities.
