Automatic update from web-platform-tests Add 'none' keyword for upper/lower bounds of clamp() clamp(MIN, VAL, none) is equivalent to max(MIN, VAL) clamp(none, VAL, MAX) is equivalent to min(VAL, MAX) clamp(none, VAL, none) is equivalent to just calc(VAL) Spec: https://drafts.csswg.org/css-values/#funcdef-clamp Fixed: 329302148 Change-Id: I1b0456b289e90bf540fce1e299c52f50891a6823 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7516844 Reviewed-by: Daniil Sakhapov <sakhapov@chromium.org> Commit-Queue: Munira Tursunova <moonira@google.com> Cr-Commit-Position: refs/heads/main@{#1575210} -- wpt-commits: 4af83765a2f5708bd7a8534a4db5d659b2cf6619 wpt-pr: 57357
