[tgauth]

The ecdsa_sk is intended for fido auth via a security key, and the verification is to confirm the user's presence.
Any usage of ecdsa_sk with Windows Hello is not officially supported yet.

In steps 3 and 4 of the repro, is the key being used for authentication? If so, the verification would be expected.
