Don't you also need (push 'eshell-tramp eshell-modules-list)?

Once I do that, I'm able to reproduce #27167, but not this bug:

    ~/src $ sudo /bin/cat foo
    /sudo:address@hidden:/home/npostavs/src/bin/cat: command not found
    ~/src $ cd /tmp
    /tmp $ sudo ls a/b
    a/b

Possible.  Does this work from M-x shell?  Does C-x C-f /sudo::/tmp/a/
work?  Does it make a difference if you run from the terminal vs running
graphically (there's at least one macOS bug where this makes a
difference, #21573).
