ssh-agent certicates not loading id

[cdstg]

"OpenSSH for Windows" version 7.7.2.1 Client OperatingSystem Windows 10 Home 1809 What is failing When I have both a cert and a id eg like id_rsa id_rsa-cert ( ecdsa versions ) it says loaded eg ssh-add It says added Key and Cert

Identity added: C:\Users\Asus/.ssh/id_rsa (C:\Users\Asus/.ssh/id_rsa) Certificate added: C:\Users\Asus/.ssh/id_rsa-cert.pub (vault-root-:xxxxxx)

BUT only adds the cert

PS C:\Users\Asus> ssh-add -l 2048 SHA256:Em8Fxxxxxxx C:\Users\Asus/.ssh/id_rsa (RSA-CERT)

if I do this in Ubuntu even on WSL it works as expected even with older versions of openssh

Expected output ssh-add -l 2048 SHA256::Em8Fxxxxxxx /home/craig/.ssh/id_rsa (RSA) 2048 SHA256::Em8Fxxxxxxx /home/craig/.ssh/id_rsa (RSA-CERT)

Actual output PS C:\Users\Asus> ssh-add -l 2048 SHA256:Em8Fxxxxxxx C:\Users\Asus/.ssh/id_rsa (RSA-CERT)

Any ideas while on native version is does not work ?
