Hey Andreu Botella

I've had a deeper read of the WEB-INTEGRATIONS document and especially at the Events section. I'm interested in the difference between the "Browser-originated dispatches" and "Asynchronous dispatches" and specifically what is meant by 'where the event originates from JS calling into some web API'.

What constitutes a JS call into a web API here? Is it only explicit function calls, as given in the XHR examples? Or would it include events fired implicitly by the rendering of components.

The example I have in my mind is the following:

We have a component that renders something, and that component has an animation defined in css. Work is done after the transition is completed, via 'transitionend' event. That can obviously happen from a number of different paths.

Would the context that scheduled the work be considered 'some web API'?
