Automatic update from web-platform-tests Make some scroll-animation tests not rely on dirty-tree snapshot An HTML PR[1] is attempting to move snapshotting of post-layout state to where the layout tree is actually clean. The plan is for the scroll-animations spec to also be expressed in terms of post-layout state snapshotting. The test changes here makes them valid both when timelines are updated before the rendering update, and when they are only updated post-layout. This CL starts with a few edits to check if this is an acceptable approach.
