Pasting in Map code doesn't work in upfront panino

Trying the map widget, awesome!

dropped the widget in
front end asks me to put in my google maps ID, I don't want to do that its a big funcking hastle
go to setting for the app,
click the check box for "use custom map code"
open map code panel
paste in map code generated on google maps:
<iframe src="!1m18!1m12!1m3!1d3307.7862426794577!2d-118.4815184847865!3d33.998023880620785!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x80c2bace19debd65%3A0xcaac5ea82a3d5346!2s3101+Main+St%2C+Santa+Monica%2C+CA+90405!5e0!3m2!1sen!2sus!4v1479759143397" width="600" height="450" frameborder="0" style="border:0" allowfullscreen></iframe>

Click save...not rendering map.

I open the inspector on chrome, bug:

Uncaught SyntaxError: Unexpected token < in JSON at position 0
