Created attachment 157320 [details] Reduction If a style element inside a shadowRoot defines an animation via @-webkit-keyframes, the animation does not run when used within the shadowRoot. However, if a style element inside a shadowRoot refers to an animation in a document style element, the animation does run when used within the shadowRoot.

As styles in a shadow DOM subtree are treated as "scoped" and all scoped @keyframes are ignored (c.f. bug 72462), @-webkit-keyframes declared in a shadow DOM subtree doesn't work. c.f. StyleResolver.cpp // FIXME (BUG 72462): We don't add @keyframe rules of scoped style sheets for the moment. if (scope) continue; resolver->addKeyframeStyle(static_cast<StyleRuleKeyframes*>(rule)); and <style scoped>: Implement scoped @keyframes https://bugs.webkit.org/show_bug.cgi?id=72462 Best regards, Takashi Sakamoto (In reply to comment #0) > Created an attachment (id=157320) [details] > Reduction > > If a style element inside a shadowRoot defines an animation via @-webkit-keyframes, the animation does not run when used within the shadowRoot. > > However, if a style element inside a shadowRoot refers to an animation in a document style element, the animation does run when used within the shadowRoot.
