`JweRsaKeyEncryptionDecryptorImpl.Decrypt` passed the JWE's initialization vector to `cipher.AEAD.Open` without checking its length. The Go standard library **panics** rather than returning an error when a GCM nonce is not exactly `NonceSize()` bytes, so a JWE carrying a wrong-sized IV crashes the decrypting goroutine.
