To reproduce, navigate to the URL and start scrolling the page down. In the sidebar on the right hand side, there are several boxes with blue headers, each showing three video thumbnails. After r110080, three additional thumbnails are rendered outside the box, to its left, overlapping other page content. This should not happen, as the boxes specify overflow: hidden. This was most likely caused by <http://trac.webkit.org/r110072>, the fix for bug 75568.

Julien, please consider reverting r110072 if you cannot come up with a fix for this bug and for bug 81802 soon.
