Seems like there's still a need for a test

I will leave the TODO. It is not currently testable though through key import,
since no key type supporting deriveBits is implemented. When DH/ECDH are added I
can address this.

   const TestCase test_case[] = {
       {"encrypt", "A128CBC", aes_cbc_algorithm,
        blink::WebCryptoKeyUsageEncrypt},
