> WPT were updated already by Chromium WPT export I don't think the tests are entirely correct. In particular, https://wpt.live/css/selectors/selectors-4/lang-singleton-subtag-matching.html has tests that expect to match the tags `fr-x` and `zh-x`, but AFAICS according to [BCP47 syntax](https://www.rfc-editor.org/rfc/rfc5646.html#section-2.1) these are ill-formed: the `x` singleton that indicates private-use is _only_ allowed if followed by a further subtag. -- GitHub Notification of comment by jfkthame Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/8720#issuecomment-4297838351 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
