Current method CryptoAlgorithm::importKey is defined as follow: void importKey(SubtleCrypto::KeyFormat, KeyData&&, const std::unique_ptr<CryptoAlgorithmParameters>&&, bool extractable, CryptoKeyUsageBitmap, KeyCallback&&, ExceptionCallback&&); A const rvalue reference makes no sense here. Therefore, I propose it should be rewritten as: void importKey(SubtleCrypto::KeyFormat, KeyData&&, const CryptoAlgorithmParameters&, bool extractable, CryptoKeyUsageBitmap, KeyCallback&&, ExceptionCallback&&);
