Form not showing Success state

Hello,

I’m using a form that with a POST action to an external URL. The action opens in a new window. Everything is working properly. However, is there any way to make the form enter the “success” state after POST? As it currently works, when you return to the original page/tab, the form is still filled out. I’m concerned this will confuse people or lead to duplicate submissions.

Thanks!
