"OpenSSH for Windows" version
7.7.2.0

Client OperatingSystem
Windows 10 Enterprise (1709)

What is failing
I've installed the 'ssh-agent' service. I call ssh-add to add my key to the agent. I'm asked to provide my passphrase, which I do. When I use the ssh command I get warning: agent returned different signature type ssh-rsa (expected rsa-sha2-512).

Expected output
No warning.

Actual output
warning: agent returned different signature type ssh-rsa (expected rsa-sha2-512).
