There was either a CSS issue / HTML issue with this commit, where one of the list items wasn't being wrapped up thus causing the WikiFont to be misaligned, along with the list item itself (if I remember correctly). Note to self - check out the commit which is available on social-tools.wmflabs.org (for testing it out) and see if this is still true, and then let's figure out how to solve it. :)
