Automatic update from web-platform-tests Add tests for direction and bidi isolation behavior of <slot> element. These tests are based on the tests previously in https://crrev.com/c/4800075 and https://crrev.com/c/4973701, but are revised to reflect that the HTML spec changes that those changes were implementing have been reverted in whatwg/html#9880 Bug: 576815 Change-Id: Id4536cb39691c2d234113f891f96d7100c7eeea4 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5233352 Reviewed-by: Di Zhang <[email protected]> Auto-Submit: David Baron <[email protected]> Commit-Queue: Di Zhang <[email protected]> Cr-Commit-Position: refs/heads/main@{#1251783} -- wpt-commits: 41bbcfcc813d99401ca0cacfa392c87d6f18ffca wpt-pr: 44178
