Why do you think it is a bug? Mixed case is allowed and may be
significant in the local part of email addresses. If you subscribe an
address with a mixed case local part to a Mailman list, Mailman stores
two addresses - a lower-cased address which is used as the key to
identify the member throught Mailman, and a case-preserved address
which is used as the delivery address. It would be wrong for Mailman
to deliver to the lower-cased address.

And it should, but it seems that it may not be in this case, BUT are
you sure Postfix dropped these addresses. Maybe you just didn't see
them in the logs because you were looking for the lower-cased address
and what was logged was the mixed-case address.

If you go back to your original bin/list_members and add a '-p' option
to it, you will get the list of case-preserved addresses that Mailman
actually delivered to and you might find them all in Postfix.

Yes, as I note above.
