I'm wondering how the tests ran on integration w/o any problems.

Do we need to add postMessage for ServieWorkerClient?

There are some other like CrossOriginServiceWorker (I guess that's
_DOMWindowCrossFrame)?

What about postMessage in CompositeWorkerGlobalScope?

Noticed we never did this for ServiceWorker in 39/45 there is a postMessage
shouldn't that have been there too?

There is a postMessage in ServicePort for 45 should that be here too?

And what about Worker it was in 39 and there's still a postMessage in 45?

Good question. Maybe there's some interaction with something else that happened
on master in between?
I don't see that class. But this covers everything in dart:html, except that it
turns out for _DOMWindowCrossFrame it's from template and I need to fix that
one.
CrossOriginServiceWorkerClient gets generated correctly without the special case
here.
I think you mean Compositor...  That's in there, it's the second one in the
list.
As above, everything in dart:html should be good now.
