Hi,I am evaluating a migration from mbox.js to at.js and have encountered an issue. I have replaced mbox.js to at.js with an auto create mbox setting.When I try to setup an experience using form based setup: any javascript in the HTML offer works perfectly but if I add some html for e.g.:" hiii " , it does not appear anywhere on the page.With mbox.js I was able to view the HTML offer in the target-global-mbox div on the page. Where exactly does at.js create an mbox, and why is this mbox not vi...
