This implements the proposed spec clarification in http://lists.w3.org/Archives/Public/www-style/2013Feb/0229.html which makes us compatible with WebKit on the insertRule tests in this patch. I confirmed that the test reports 7 failures without the patch, but passes with the patch. (I'm a little disturbed by the way our testharness.js integration elides runs of successive passes.)
