Thanks for this precision. Now I'm able to reproduce the problem, even
with older Emacs versions.

As far as I could debug, sometimes Tramp is not involved. You could see
it when you instrument the test via

(trace-function-background 'find-file-name-handler)

When you copy a remote directory from dired, there are entries in
*trace-output* like this:

--8<---------------cut here---------------start------------->8---
1 -> (find-file-name-handler "/ssh:localhost:/home/albinus/.emacs.d" 
copy-directory)
1 <- find-file-name-handler: nil
--8<---------------cut here---------------end--------------->8---

But the result shall be

--8<---------------cut here---------------start------------->8---
1 <- find-file-name-handler: tramp-file-name-handler
--8<---------------cut here---------------end--------------->8---

No idea what's up. I need more debugging; unfortunately I have to start
for a business trip just now. When time permits, I'll continue next days.
