Hi. We're trying to test a widget embed in your site, but it seems the iframe is possibly being embedded in another iframe, when in the site editor mode. Which is strange, because when the page is published, it actually displays the widget: http://testandu.broadsheet.io/544a10fa5065790200338377 http://testandu.broadsheet.io/544a10fa5065790200338377 On our platform we're testing the referrer to make sure there's no unauthorised embeds, we cannot access it hence we cannot preview widget in the site editor mode.
