Re: [csswg-drafts] [css-animations-2] Move scroll and event animation triggers to independent namespace (#12336)

From author POV I'd expect `preventDefault()` to not prevent a specified animation trigger from acting on an animation.

> The reason I'm asking this is that from an implementor's perspective, I expect the idea would be that we could have all the information for animations to be started via an animation trigger stored in a separate thread / process and act on them without involving the web process / main thread. But I don't understand how this is feasible given the complexity of event dispatch.

I guess @szager-chromium could answer?
