I can reproduce the behavior in Thunderbird 52.2.1 with this message.

I get the same behavior via pressing <Ctrl>-<r> and clicking the reply 
button, both of which reply to the OP, /not/ to the list.

I do have a button "Reply List" which seems to use the List-Post header.

It's been a while since I set up a Mailman mailing list, but I seem to 
remember having Mailman add a Reply-To and direct the replies to the 
mailing list / List-Post address.

I don't think this is a Thunderbird problem per say.  Reply "to sender" 
and reply "to list" are two distinct things.

To me, this is a user education issue -or- a mailing list configuration 
issue.  (Sorry, I can't point to how to reconfigure things.)
