-----------
[scroll-animations] crash under
`StyleOriginatedTimelinesController::unregisterNamedTimeline()` due to iterator
mutation

Reviewed by Pascoe.
Ensure we make a copy of a timeline's animations before we iterate over it
and possibly mutate it under `CSSAnimation::syncStyleOriginatedTimeline()`
which can call `WebAnimation::setTimeline()` and change the very timeline
animation list we're iterating over.
