Automatic update from web-platform-tests Fetch: blocking opaque 416 responses to range requests See https://github.com/whatwg/fetch/pull/1907 for context. We use an image instead of JavaScript as JavaScript requires a 2xx status whereas images don't care. Also remove a redundant null check from useStoredRangeResponse() and a redundant catch() elsewhere. -- wpt-commits: e3661ee657a61122b3026e8eaaba31cbddd7a9a8 wpt-pr: 57225
