Thanks for the report, I can confirm the behaviour. However, this is not
a bug. Try the following command instead:

emacs -Q --eval '(setq tramp-verbose 6)'

This enables traces up to level 6, which are the commands send to a
remote host. You will see also the buffer *debug tramp/ssh...*. No trace
there with level 6, but entries like

11:09:33.148026 tramp-file-name-handler (5) # Non-essential received in operation (file-name-all-completions  /ssh::)

This tells us, that Tramp hasn't tried any remote connection, because it
is still in user name / host name completion. And that's what counts.

I'm marking this as not-a-bug, and close it. Feel free to ask if you
need further information.

Best regards, Michael.
