Seamless, isolated srcdoc-iframe in Internet Explorer

I am currently stuck with a simple task. All I want to do is create an isolated, seamless iframe. It works fine in Chrome and Firefox, but in IE (11) it looks blank:

<iframe sandbox="allow-same-origin" seamless srcdoc="<p>Yay!</p>"></iframe>

      

        
        
        
      

    

I read that IE supports the property security

, but the same result.

So here's the fiddle: http://jsfiddle.net/SoftCreatR/o30mf2cq/

Any idea how I can get it to work in IE10 +?

EDIT:

I seem to have found a working solution: StackOverflow question.
