Just like how we handle the CSSAnimation and CSSTransition. We use TimelineCollection to store the named progress timeline objects created by scroll-timeline-name and view-timeline-name, and reuse ElementAnimationData to handle the life time of TimelineCollection. Also, introduce TimelineManager to update timelines generated by CSS. We add one test which mutates the scroll-timeline-axis to make sure we restyle the animations associtated with the existing timelines. It will be passed when we start to use the new framework, in the next patch. Differential Revision: https://phabricator.services.mozilla.com/D169271
