Indeed, it happens since then.

I'm very sorry, but this is a special case. Usually, we appreciate much
to run the tests with "emacs -Q". However, it happens often that I have
to debug Tramp problems which are related to cached properties, or
passwords. That's why Tramp neither loads cached properties, nor uses
auth-sources when Emacs is called with "-Q".

I'm pretty sure this problem doesn't happen when you start simply "emacs".

Best regards, Michael.
