Automatic update from web-platform-tests Use the frame `Accept` header for prefetches. Special-casing prefetches makes it so that `Vary: Accept` makes the browser erroneously reject the prefetched response. Also changed the SXG ?q= value for the frame accept header, as it was done for prefetch (and should have been done for the frame accept header). For now CORS prefetches remain untouched, as changing them to the >128bytes frame accept headers would cause incompatibility due to a CORS-preflight requirement. This was previously unspecified, See https://github.com/whatwg/fetch/pull/1485 Bug: 626081 Change-Id: I2c99f4f1abd2556fdf456d877588b346a22fd677 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/4069726 Reviewed-by: Matt Menke <mmenke@chromium.org> Commit-Queue: Noam Rosenthal <nrosenthal@chromium.org> Auto-Submit: Noam Rosenthal <nrosenthal@chromium.org> Cr-Commit-Position: refs/heads/main@{#1083806} -- wpt-commits: 9eb3b189dae1f06fed09df71442227527b860c6b wpt-pr: 37469
