This looks like an attempt to use your local key, but it failed (w/o an
error) ...

... and continued to send a public key ...

... and it asked for a password.

Here it shall call ssh-askpass like in Tramp. Strange, that it
didn't. Was the shell you have used for test in the same X11 session as
Emacs?

What happens, if you call ssh in Tramp as well with -vvv? You need to
modify the respective entry in tramp-methods, like this:

Restart Emacs from scratch, and try.
