Identity Chooser supports two modes: 1) either you have to choose the sender address for your reply or forward using the drop down menu; 2) in Identity Chooser's settings you can disable the drop down menu for reply and forward. In this case, Thunderbird's default behavior kicks in which means, the sender of your reply or forward should be the address the email was sent to.

So: Please configure Identity Chooser such that it suits your needs. Should I misread your review and you meant something else, please open an issue at Identity Chooser's github and I'll see what I can do.
