Comment on attachment 103562 [details] Patch Is there some way to test the performance benefit here? Maybe we could do a performance test that checks that changing the value back and forth and forcing style recalculation is significantly slower than setting the value to the same thing over and over again. It would be great to have a test like that!

Even if this were slower I think it would be worth doing. When I first started touching the m_fontDirtry logic it was really because I wanted it to not be spread all over the place, because I figured it would be too easy to accidentally not set m_fontDirty. It still is, but at least the logic is constrained to fewer places. Thanks for the review!
