[scroll-animations] changed `timeline-scope` values should update timelines
for animations globally
https://bugs.webkit.org/show_bug.cgi?id=323073
rdar://186331685
Reviewed by Anne van Kesteren.
Because style-originated timeline would only match within an animation's target
ancestor chain,
or in the subtree of an element with a `timeline-scope` property, we would only
consider the hierarchy
of the element that had its `timeline-scope` change. Now that style-originated
timelines match
globally [0] we must update any animation for a name contained in the
`timeline-scope` property
that changed.
This fixes the final failure in the WPT test
`scroll-animations/css/timeline-scope.html` introduced
by the WPT changes in https://github.com/web-platform-tests/wpt/pull/61776.
