Comment on attachment 375619 [details] patch View in context: https://bugs.webkit.org/attachment.cgi?id=375619&action=review > Source/WebCore/css/DocumentRuleSets.h:79 > + static bool s_isInvalidatingStyleWithRuleSets; I am unclear why it is OK for this to be a static. I do not think DocumentRuleSets are process-global, are they?
