Forms are not render in full height

This is only happening to the publisher. In author, it's perfect. Our CSE has installed SP13 and followed with form addon installation. But after that, forms on publishers are not render in full height. It's shrinking in the iFrame. Also, some of the form controls stopped working, such as checkbox is not checkable and captcha is not rendering. 

I found a similar post here: https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager-forms/aem-form-not-rendering-in-iframe/m-p/300519#M2489

Are we missing any addons? Is there a specific package we should look for? Is there any configuration missing on the publishers?
