Web page that reproduce the issue

When I add a data attribute to an element via a click event and that I've set a style rule that apply based on this data attribute. On any webkit version I've tried (Safari/Chromium included), the style is not applied.
This works on Firefox 4b7.

Not sure my explanation is clear enough so here's a test page to reproduce it: http://www.jeremyselier.com/s/bug/css-datavar
