There was a spec change to have @property registrations in shadow dom be globally registered: https://drafts.css-houdini.org/css-properties-values-api-1/#shadow-dom I have changed the one WPT test that covered this to match the updated spec: https://github.com/web-platform-tests/wpt/blob/master/css/css-properties-values-api/at-property-shadow.html https://issues.chromium.org/issues/40066407#comment1 has one example of the motivation behind the spec change.

See https://github.com/w3c/css-houdini-drafts/pull/1085, I think this probably needs more details about how it works.
