Has anyone managed to reproduce the OP's results, either getting

On Debian 11, when I create a test user, login on a console as that
user, and duplicate the recipe provided in the original message[1],
the reported problem does NOT occur:
Aha...
so main suspects are now ~/.bash_profile ~/.inputrc or some exported

This just gets weirder and weirder.
It looks like it's related to logging in with ssh:
I am running a modified ssh. It's been patched to allow cipher None and
I've backported from sid
I had to jump through some hoops to login at the console but now:

Downgrading ssh back to the version from bullseye shows it's not my
