PRIMARY (continue) button re-enabled by Authnet js library before submission completes

Problem/Motivation

The primary button for a checkout step is re-enabled by commerce_authnet/js/commerce_authnet.accept.form.js (~ line 181) before submission making it seem as though the submission was not successful. This also allows a user to click the submit button again while the form is still submitting.

I understand there is likely a reason for this action, but am looking for a way to keep the button disabled until the page has successfully submitted and the user is redirected to the next step in the checkout workflow.
