Rationale

I'm currently documenting customizable select elements on MDN, and many of the new CSS features are specced here.

Changes to index.json

This update would not trigger any change in index.json.

Tests

These changes look good! 😎

The spec is already in browser-specs in practice. Now, the spec says it is an "Unofficial Proposal Draft", so the entry gets a "standing": "pending" property, and I suppose "pending" specs get skipped in BCD. Ideally, the fix would be that the spec stops saying that it is an unofficial proposal draft, especially if it is already implemented somewhere. In the meantime, we'll have to force the standing to "good" in browser-specs.

Done. This should be enough to make the spec appear in BCD. Let me know if that's not the case!
