Description Jake Archibald 2018-05-29 06:42:28 PDT 
Spec change: https://github.com/whatwg/fetch/pull/560.
Tests: https://github.com/web-platform-tests/wpt/pull/10348.
Security issues to pay attention to: https://github.com/whatwg/fetch/issues/144#issuecomment-368040980

This spec change means that rage requests (such as those from media elements) are allowed to pass through a service worker as long as they aren't modified. This fixes a long standing issue where media elements behave oddly if intercepted by a service worker (as the range headers were lost).

How media elements ingest partial responses remains unspecified for now. See the attacks in https://github.com/whatwg/fetch/issues/144#issuecomment-368040980 & their mitigations. Attack 4 is already covered in the tests.
