Bug 1769191 [wpt PR 34051] - Support invalidation for location pseudo…

… classes inside :has(), a=testonly Automatic update from web-platform-tests Support invalidation for location pseudo classes inside :has() Support invalidation for :link, :any-link and :target pseudo class inside :has(). Invalidation for :visited inside :has() is not needed since :visited is not matched inside :has() to prevent leaking visitedness. Ignored invalidation of :scope inside :has() due to an issue in the csswg-draft. - w3c/csswg-drafts#7211 Bug: 669058, 1324834 Change-Id: Ice42f0113f0cdc69a8054c2778c9cab3cdd5ef10 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3645177 Reviewed-by: Rune Lillesveen <futhark@chromium.org> Commit-Queue: Byungwoo Lee <blee@igalia.com> Cr-Commit-Position: refs/heads/main@{#1003038} -- wpt-commits: 4b68c346624989cf904a632a862fd54520adb1fc wpt-pr: 34051
