(In reply to Sam Weinig from comment #4) > What does it mean this covered by existing tests? Do those tests change > their results? crypto/subtle/ecdsa-import-key-verify-p384.html fails in Internal Bots. After this change, it should pass. That's why this change is covered by existing tests. Please see radars for further information.
