The `AnimationTimelinesController` code related to `timeline-scope` attachment operations has multiple call sites for its `attachPendingOperations()` method which processes pending operations. However, we need to wait for a document's style resolution to have completed to be able to correctly process those operations, so we should make things both simpler and correct with a single class upon style resolution completion.
