title: Microsoft Edge not displaying <iframe>
body: <p>I have a button that creates a new tab and loads some simple HTML and an iframe with a data URI passed into it. The new tab opens and I can see that this is all displayed in the DOM using the navigation tools (F12). However the Iframe does not display in Edge browser. I receive the error<code>HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).</code></p>
  
  <p>Below image shows the DOM and that everything is loading as expected.</p>
