How to make Lightbox Thank You Page scroll to top

I have embedded three forms on my website - each as a lightbox. The forms work beautifully, except for one issue: after hitting the submit button, the Thank You pages are scrolled down into a blank area. 

Is there a way to have the Thank You Pages automatically scroll to the top so the user can see the thank you text?

I tried to fix this, but I could not find a way to make the Thank You page load at the top of the lightbox popup modal. I have escalated this to our back-end team to get further help. You will be updated via this thread.

We can send this feature request to our backend team. However, we cannot tell if they will implement your request and when. So an alternative is to do the following:

While on edit mode for each form: Go to Settings > Thank You Page > Redirect to external link.

You can paste the link to the same page or to a customized Thank You page.
