Created attachment 278399 [details] Page with css statement applied Although the tab lockup of #148573 seems fixed in Safari 9, it seems that it is incorrectly measuring the width of inline elements (spanning multiple lines ???). Content overflows outside of the expected boundaries and random spacing is introduced between words. Attached are a screenshot of a page with -webkit-isolate enabled on the .comment class, a screenshot with the rule disabled and a webarchive of the page. This problem does not occur in Chrome.

Safari, Chrome, and Firefox all agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
