Automatic update from web-platform-tests Ship @supports selector() Unfortunately, some animation tests are now failing, because the tests use CSS.supports to query for ::marker support, and change their behavior to include ::marker animations. Animating ::marker is currently not allowed by the spec, and therefore not supported by Blink.
