The default test is [ $TERM = "dumb" ]

That might be a problem, indeed. But first let's test whether setting a
simple prompt helps you.

Not really. Tramp, for example, sends "unset HISTORY", and it sees your
prompt with the escape sequence. So please, as a first test, discard any
special prompt setting on the remote side, and see whether Tramp goes
through. If this test succeeds, we can investigate how you could
tetermine the presence of Tramp, if the test for $TERM is not
applicable.

If not, then we must continue with the EOL issue.
