After form submission, submission message is out of view

We have an airtable form that we are embedding into our website via an iframe. Our form is very long and after they submit it we run into weird behavior.

  1. Submit a very long form
  2. webpage remains the height of the form
  3. submission message is centered within that height
  4. screen appears to be blank (causing confusion wether the form has been properly submitted)
  5. Scroll up you will see the after submission message.

Why does the height of the webpage stay the same after the form is submitted? It is causing the message to be “hidden” from view and causing confusion.
