Re: [w3c/ServiceWorker] activation of the Service Worker on an iframe context (#1029)

I think I know what's going on. Does the domain.com service worker have a fetch event handler? If not, then Chrome 54+ does not start it up for the navigation. This is an optimization, since the request will just go to network anyway. You can check this by finding the registration in chrome://serviceworker-internals and checking the field "Fetch handler existence".
