Relative font size values (em) within CSS animations compound https://bugs.webkit.org/show_bug.cgi?id=194749 <rdar://problem/48171898> Reviewed by Antoine Quint. Source/WebCore: The em unit should be relative to the font size of the parent style when resolving 'font-size' property. We weren't passing the parent style when resolving keyframes. Test case by Scott Kellum. Test: animations/keyframe-em-unit.html * style/StyleResolver.cpp: (WebCore::Style::Resolver::styleForKeyframe): * style/StyleResolver.h: (WebCore::Style::Resolver::overrideDocumentElementStyle const): (WebCore::Style::Resolver::setOverrideDocumentElementStyle): (WebCore::Style::Resolver::setParentElementStyleForKeyframes): Add a way to pass the parent element style directly to the style resolver. This should really be passed via the animation system like other context but that requires lots of refactoring. * style/StyleTreeResolver.cpp: (WebCore::Style::TreeResolver::createAnimatedElementUpdate): Pass it. LayoutTests: * animations/keyframe-em-unit-expected.html: Added. * animations/keyframe-em-unit.html: Added.
