Simplified Welcome View does not support html ?

Hello, 

I have an issue concerning the simplified view, it would seem that it doesn’t support HTML, or just partly ?

When sending an envelope via docusign API, i am sending HTML through the “emailBlurb”, that html is well rendered on the email side. But it is not on the docusign simplified preview page
On the email side:
 

On the simplified welcome view, many spaces generated, images doesnt work.
 

I was wondering if it was possible to disable the simplified view, or to remove the html from this page. 

Thank you for your help !
