Created attachment 312428 [details] Symbol CSS Animation Test Case CSS animations are not run for elements inside <symbol> SVG elements. The attached 'Symbol CSS Animation Test Case' shows three rectangles. The red ones are symbols and the green one is not. Only the green one is rotating. I would expect to see all three rectangles rotating. Chrome and Firefox show all three rectangles rotating. Tested on Safari Technology Preview Release 32 (Safari 11.0, WebKit 12604.1.23.0.4) and Safari 10.1.1.

Hi, thank you for your work. We seems experiencing the same problem, CSS animation doesn't work for us inside SVG `symbol`s when inserting with `use` element. Test case: https://codepen.io/iamobstinado/pen/zYwvaXW?editors=1000 Tested in browsers: macOS Catalina (10.15.7) * Chrome 91.0.4472.114 ✅ * Firefox 89.0.2 ✅ * Safari 14.1.1 ❌ macOS Big Sur (11.4) * Chrome 91.0.4472.114 ✅ * Firefox 89.0.2 ✅ * Safari 14.1.1 ❌ ✅ – animation works ❌ – animation doesn't work Is there any updates, is it expected behaviour according SVG specs?

It is not working on WebKit ToT (260935@main) as well. Works fine in Chrome Canary 113 and Firefox Nightly 112.

Somewhat surprisingly, this progressed with 300706@main, the fix for bug 296048.
