I normally don't exit the container after a build so it should be
happening there as well, but it didn't for me.
I might have to spend some time testing with different packages in
order to reproduce this, but I am pretty sure I tried installing
openssh before.

Since installing debian via chroot and debootstrap is one of the
official supported ways of doing it, I would suspect that starting
daemons within that environment should be prevented upstream.

Maybe take a look at how the debian-installer handles this?
