Automatic update from web-platform-tests Cleanup sec-ch-width auto sizes tests This patch makes the following test cleanups for sec-ch-width auto sizes tests: * Delete sec-ch-width-auto-sizes-002.https.html which is no longer testing a useful codepath (everything is covered in -001). * Remove an unnecessary media query from -003 that could fail on some viewport sizes. * Rename -001 -> -img, and -003 -> -picture. Thanks to Eric Portis for spotting these in https://chromium-review.googlesource.com/c/chromium/src/+/5531414/5#message-2509e3e290ac9bf9afca14f19739ab6bd8eab35c Bug: 335630145 Change-Id: Idfc39a00e82cb0d25b842c90022fb3bf48f9b32d Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5552524 Commit-Queue: Traian Captan <[email protected]> Reviewed-by: Traian Captan <[email protected]> Auto-Submit: Philip Rogers <[email protected]> Cr-Commit-Position: refs/heads/main@{#1304038} -- wpt-commits: 5b7a1a44887d1c68ad67a4df894febd45f520c2a wpt-pr: 46416
