Enter in STP 191 data:text/html,<div%20style="animation:none"></div> In the Web Inspector console, type document.querySelector('div').style.getPropertyValue('animation') It returns 0s instead of none. This fails the test http://wpt.live/css/css-animations/parsing/animation-valid.html http://wpt.fyi/css/css-animations/parsing/animation-valid.html Firefox and Chrome return the correct value.

This test was added in https://github.com/web-platform-tests/wpt/commit/ec49f0a0b605c79a343c9e6a12126502cee58638 and is related to the change in the CSS Animations spec to report `auto` instead of `0s` as the default animation-duration value. Compare and contrast: https://drafts.csswg.org/css-animations-1/#animation-duration https://drafts.csswg.org/css-animations-2/#animation-duration This is part of the scroll-linked animations work.

Everything is green on. http://wpt.fyi/results/css/css-animations/parsing/animation-valid.html BUT data:text/html,<div%20style="animation:none"></div> document.querySelector('div').style.getPropertyValue('animation') NOW returns on STP 230: "auto" Firefox: "none" Chrome: "auto ease 0s 1 normal none running none"

Both the WPT tests listed are green on Safari (and Firefox). Should we close this?
