Unfortunately, the patch doesn't help.
By the way, this is what I noticed:
* the issue seems to occur more often in a docker container
* over /ssh it is working well, or at least it never occurred
* the temporary buffers like ~/tmp/tramp.J0RZDc~ are actually created on remote
* after repetitive tests I noticed that it doesn't reproduce anymore
and I added a line to print the default-directory right before
`make-process` for stderr: ~lisp/net/tramp-sh.el:3057~
  - when it fails, the default-directory is on local host
  - when it succeeds - it's on remote (where I guess it finds that
temporary file)
* on emacs restart it starts reproducing again
* once it starts working, it never reproduces again until emacs restart

It looks like it has something to do with `stderr` process execution
environment.
