WSManStackVersion              3.0

Its neither working with online feature openssh nor the newest installed via msi. Uninstalled, restarted and reinstalled both independently.

Expected behavior

ssh -T git@github.com
using ed225519 from agent... 
bla bla from github server (no cli)


It should use only the identities from ssh-agent 
ssh.exe and ssh-add.exe are started both from default installation directory C:\ProgramData\ssh

Actual behavior

DE\C:\Users\[me]> ssh-add -l
`256 SHA256:... ed25519-Githubkey-20240110 (ED25519) `

Reproduce the report on Windows 10 with OpenSSH_for_Windows_9.5p1 and PowerShell 7.4.1: first run ssh-add -l, then ssh -vT git@github.com from the default installation directory. Compare the agent identities with the verbose connection output; done means ssh uses the listed ssh-agent identity and completes the GitHub test connection.
