Issues with embed

Hello.

Just recently, the embed instructions noted here have stopped working:
https://help.calendly.com/hc/en-us/articles/223147027?tab=advanced#3

Using the invocation code:

Calendly.initInlineWidget({

                url: 'https://calendly.com/d/FORMIDREMOVED?hide_gdpr_banner=1',

                parentElement: document.getElementById('calendly-modal-body'),

                prefill: {}

            });

Spawns a request to Calendly that ultimately returns this response

X-Content-Type-Options: nosniff

X-Frame-Options: DENY

The X-Frame-Options: DENY is the kicker, since the Calendly.initInlineWidget call spawns within an iFrame.

In other words, the javascript says: load _this_ in an iFrame

The iframe body request says: no iFrames allowed.

New bug?
