the method, instead of setting them before calling the method. That way we can avoid reflowing the ancestor of a reflow root which is not itself dirty but has dirty children. This also makes it harder to set dirty bits inconsistently with the FrameNeedsReflow call. Bug 378784, r+sr=dbaron, pending rbs' review on the mathml parts. git-svn-id: svn://10.0.0.236/trunk@226007 18797224-902f-48f8-a5cc-f745e15eee43
