(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I tried reproducing this under "emacs -Q" with Emacs 28/29, but Tramp
pops up the full ssh message buffer, so I don't seem to be able to
reproduce the problem.  Are you still seeing the problem in recent Emacs
versions?
