failing test case: YUI reset CSS

This is new as of merging @eoln 's pull request. It's not really his fault, this test case wasn't in the suite, and it's a result of updating jsdom to a newer version. I think to fix this we're going to need to update jsdom *all the way* to the newest, and then re-evaluate this and other failed test cases.
