Interesting.  I’ve only noticed it in 25.2 and 25.3 on macOS (installed from brew).  I can’t reproduce it in 25.2 on Ubuntu 17.10.

This is reproducible for me too on macOS.

I can also reproduce it by running the Mailman 3 shell from git checkout.  That made me think it could be readline related, but I built a Mailman 3 without readline support and it made no difference.  I haven’t figured out what the common denominator is, but I edebug’d it down to comint-send-string and then process-send-string.  There the trail ended with C code and I haven’t gdb’d into that.  It seems like some state in process-send-string gets confused and starts echoing the input.
