bundle.js returning iframes and sections with scrollbars for focused displayFormat

I’ve implemented an imbedded signature request integration using the javascript library https://js-d.docusign.com/bundle.js, submitting signingUrl with displayFormat as ‘focused’. It’s implementing an iframes response into the div signing-ceremony div. 

I don’t want frames or iframes. I don’t want a second scrollbar right inside the first. I want this in a div tag - no frames. It looks like the content inserted starts with an iframe with id - js-library-iframe. Inside that, there’s another html start, header, body - and another iframe - id ds-signing-document - which has yet another html start, header, body, and multiple sections - one with a scroll bar. The code coming in from the javascript seems excessively complicated when all I want is the document with the ability to sign. Is there any way I can avoid all the iframes and the section with the scroll bar? I’d like the div to just expand with the content so if a user needs to scroll, they can scroll with the browser scroll bar, and that would be it. Any way to do that? I thought this method was supposed to get us away from frames, and a complicated scrolling user interface.
