Re: [webauthn] TPM Attestation Statement Format: Missing COSE Key algorithm Identifier and clarification.

The corresponding validation procedure currently includes:
Verify that `extraData` is set to |attToBeSigned|.

Should this be changed to:
Verify that `extraData` is set to the hash of |attToBeSigned| using the hash algorithm employed in "alg".

It seems like this would be required to be consistent with the signing procedure.
