This WPT test fails on WebKit: css/css-flexbox/percentage-size-quirks-001.html The result is [1]. This TC was introduced in [2] but Chromium revised the TC and updated the expectation in favor of FF[3] behavior. FYI, If the TC has DOCTYPE, strict mode, it works as Chromium and FF.

The previous test is working fine now. Renamed the bug to address the new one.

We are still failing this test case with Safari Technology Preview 153. I don't know whether it is part of InterOp 2022 but it would be good to fix. Thanks!
