HTML Preview Regression

[madflow]

The HTML preview is broken for us with the latest releases of Maildev:

Uncaught TypeError: iframe is null
    replaceMediaQueries http://maildev.gs1.local/scripts/controllers/item.js:69
    prepIframe http://maildev.gs1.local/scripts/controllers/item.js:51
[item.js:69:7](http://maildev.gs1.local/scripts/controllers/item.js)
    replaceMediaQueries http://maildev.gs1.local/scripts/controllers/item.js:69
    prepIframe http://maildev.gs1.local/scripts/controllers/item.js:51

We use MJML. For example just copy and paste:

https://mjml.io/try-it-live

And try sending this HTML as payload.
