SSH key password not prompted for connection with SSH tunneling

[Arakmar]

I have a connection to a MySQL DB accessed though a SSH tunnel.
It's configured to not remember the password so it asks it every time.

Since 3.8.3, the password isn't asked and the connection fails with the following error :

This happens only in case of password protected private key auth.
Thanks for report.
