Re: [w3c/ServiceWorker] should prefetch loads trigger FetchEvents? (#1302)

I also filed a similar issue as https://github.com/w3c/resource-hints/issues/78. As far as I can see, the flow is not specified and not tested in WPT. @kinu described the Chrome implementation as:

1. Page A embeds <link rel=prefetch href=B>
2. B is fetched as a subresource through A's Service Worker. If this is a real response (i.e. A's SW can't fake a cross-origin response), it's entered into a HTTP cache with a minimum 5-minute lifetime.
3. User clicks link to C.
4. If C requests B, that request goes through C's SW.
5. If C's SW forwards the request to the network, it'll find the prefetched response in the HTTP cache.
