Automatic update from web-platform-tests Enabled Web Animation APIs for scroll animations - Enabled pause(), reverse() and updatePlaybackRate() APIs for scroll animations. - Provided temporary fix for play animation procedure to accommodate reverse() and replaying finished animation cases. The fix reflects pending https://github.com/w3c/csswg-drafts/pull/5059. - Ported wpt/web-animations/timing-model/animations tests that exercise the APIs. - Implemented scroll animation specific tests. Bug: 916117 Change-Id: I689e7a6d1f220ee12e7f7a6f90e54340eaa33aee Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/2194586 Reviewed-by: Kevin Ellis <kevers@chromium.org> Commit-Queue: Olga Gerchikov <gerchiko@microsoft.com> Cr-Commit-Position: refs/heads/master@{#771881} -- wpt-commits: 1afcb0f78cd1f6ec37d64f9bce4220102a6dc0a2 wpt-pr: 23533
