Form Preview shaking uncontrollably up and down.

When I preview my form in the pop-out window it is shaking uncontrollably up and down. I can preview it fine in the browser, but I seem to only be able to use the "Fill Form" option if I am working in the pop-out preview option.

I cloned your form and previewed it there, but I can't seem to replicate the issue. The form doesn't shake up and down when I check it on the preview pop-up window. Below is a recording of me scrolling through the pages of the cloned form.

Are you still encountering this issue on your end? May I ask which browser and device were you using when you encountered this issue? This will help us investigate the issue further. Can you please try clearing your form cache and your browser cache to refresh the form.

If the issue still persists, please let us know.
Thank you.
