no-touch-required not working

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

Here is my environment

• Yubikey 5 firmware is 5.4.3
• SSH Client: Windows 11 - OpenSSH_for_Windows_9.2p1, LibreSSL 3.6.1
• SSH server: Debian bullseye - OpenSSH_8.4p1 Debian-5+deb11u1, OpenSSL 1.1.1n

I create a new key in Windows 11:

ssh-keygen.exe -t ed25519-sk -O resident -O no-touch-required

I add the public key to ~/.ssh/authorized_keys:

no-touch-required sk-ssh-ed25519@openssh.com AAAAGnNrLXNzaC1lZDI1...Do=

When I try to establish a ssh session, I encounter error:

ssh manager@192.168.0.194
sign_and_send_pubkey: signing failed for ED25519-SK "C:\\Users\\engineer/.ssh/id_ed25519_sk": requested feature not supported
manager@192.168.0.194: Permission denied (publickey).

If I don't use -O no-touch-required when create key, the ssh session can start as usual.

Here is the full debug log:
