Automatic update from web-platform-tests Add multiple tests for prefetch behavior See https://github.com/whatwg/html/pull/8111#issuecomment-1229907894 Tests that: * preload/prefetch-cache.html No 5 minute rule (cache headers must be respected) * preload/prefetch-document.html No special treatment of as=document Whether Accept is left as its default value. Storage partitioning is applied, including for documents * preload/prefetch-load-event.html Does not block the load event * preload/prefetch-headers.html Whether any additional headers (Sec-Purpose, Purpose, X-moz, X-Purpose) are sent (depending on what we put in the spec) * preload/prefetch-types.html Always uses prefetch destination, and ignores as="" -- Add tests for load/error events -- Add cross-origin event tests -- Test for proprietary headers -- Add test cases for cross-origin error events -- Update preload/prefetch-cache.html Co-authored-by: Domenic Denicola <d@domenic.me> -- Fix CR comments -- Clean up doc test -- Retries in cache test -- Use script instead of fetch to de-flake firefox -- wpt-commits: 56746bfcf1b8eae23f81f69c144d54bb7441b9c6, 9e12c604be29a47a730ecdb3c1382e678eb9eca4, a221f4091d67ca56f9218929ab019b4b9c2f2302, 5fe9b213f64e80cddb5de0aa8debec29f5ab20ad, 67113e16693e30945f2d2b71a8a4b3f556fe4353, c03154bde9e293f82a631b80f841908c25927493, 18faf32573d6d83c1932167e23bb8f6c37df3eb1, 8f2af79a66aeaece84373ce5e24023edb2c55f08, 8ae300754a3dd226cd58b3fd53e270cf141c28fc, 1423a3236683cc4856158c54e9f8f29eef3d2871 wpt-pr: 35707
