   Make sure these boxes are checked before submitting your issue - thank you!
   
   - [Yes] I have checked the superset logs for python stacktraces and included it here as text if any
   - [Yes] I have reproduced the issue with at least the latest released version of superset
   - [Yes] I have checked the issue tracker for the same issue and I haven't found one similar
   
   When I am trying to embed a dashboard into a webpage using an iframe, I am not able to determine the height of the iframe so that it exactly matches the height of the dashboard to prevent a scrollbar from appearing inside the iframe without cropping it.
   The dashboard and web page that contains the iframe are NOT on the same domain.
   And, Chrome doesn't support the "x-frame-options=ALLOW FROM ..."
   
   Am I missing something ? Or, is this a feature request ?
   
   I have also found a workaround but that involves the dashboard sending a cross-domain message upon changing it's height. 
   
   I'm not sure if I'm the only one not able to figure this out or no one else is asking this.
   
   ### Superset version
   0.25.6
   
   ### Expected results
   Uncropped dashboard
   
   ### Actual results
   Cropped dashboard
   
   ### Steps to reproduce
   iframe code
   <iframe id="ss_dashboard" src='' width="100%" frameborder="0" scrolling="no" onload="resizeIFrameToFitContent(this)"></iframe>
   
   javascript code
   <script>
       var superset_iframe = document.getElementById('ss_dashboard');
       function resizeIFrameToFitContent( iFrame ) {
           iFrame.height = iFrame.contentWindow.document.body.scrollHeight;
       }
       superset_iframe.setAttribute('src', 'http://127.0.0.1:8088/superset/dashboard/5/?standalone=true');
   </script>
   
   The 2 errors I get in the console are
   1- Invalid 'X-Frame-Options' header encountered when loading 'http://127.0.0.1:8088/superset/dashboard/5/?standalone=true': 'ALLOW-FROM http://127.0.0.1' is not a recognized directive. The header will be ignored.
   
   2- Uncaught DOMException: Blocked a frame with origin "http://127.0.0.1:8000" from accessing a cross-origin frame.
