Currently we never expose the Range header on FetchEvent.request. This is because its added down in the http cache and network path here: https://searchfox.org/mozilla-central/source/netwerk/protocol/http/nsHttpChannel.cpp#4208 Its unclear if this should ever be exposed to script in FetchEvent.request. I filed a spec issue about that here: https://github.com/w3c/ServiceWorker/issues/1201
This is being spec'd. See bug 1465074.
