Using Windows 10 ssh-agent with DataGrip

Windows 10 now comes with a ssh-agent prgram to manage ssh keys. i can start the program (as a service) and use to to ssh to hosts within powershell.  but it doesn't seem to work with DataGrip. i can use ssh key pairs if i type in the passphrase manually ("Key pair (OpenSSH or PuTTY"). but if i select the "OpenSSH  config and authentication" option i get a "SSH Auth Fail" error.

has anyone been able to get this working?
