REGRESSION (r253875?): Element styles incorrect after media query evaluation changes https://bugs.webkit.org/show_bug.cgi?id=211505 <rdar://problem/62983242> Reviewed by Zalan Bujtas. Source/WebCore: If there are keyframe rules in media queries we fall back to wiping the style resolver when something changes. This fallback code didn't work correctly when a rule flipped from matching to non-matching because MediaQueryCollector bailed out and didn't create DynamicMediaQueryRules structure needed to detect something has changed. Test: fast/media/media-query-dynamic-with-keyframes.html * style/RuleSet.cpp: (WebCore::Style::RuleSet::addChildRules): (WebCore::Style::RuleSet::addRulesFromSheet): Call both push and pop even when the rule doesn't match. (WebCore::Style::RuleSet::MediaQueryCollector::pushAndEvaluate): Collect the MediaQuerySet in non-matching case too. (WebCore::Style::RuleSet::MediaQueryCollector::pop): Record the DynamicMediaQueryRules when resolving all rules statically. LayoutTests: * fast/media/media-query-dynamic-with-keyframes-expected.html: Added. * fast/media/media-query-dynamic-with-keyframes.html: Added.
