title: Iframe pdf set url throwing warning
body: <p>I am using Chrome webbrowser.</p>
  
  <p>I have scenario like this: Get application/pdf from the server, create blob, create url from that blob, create iFrame set url and append to body.</p>
  
  <p>What I get is info/warning:
  Resource interpreted as Document but transferred with MIME type application/pdf: "blob:http%3A//localhost/44655364-1927-426b-b158-04db3f0f1c6f"</p>
  
  <p>Same things happen if I will just put Iframe in index.html and set src to any pdf from internet.</p>
  
  <p>How I can get rid of this warning/info?</p>
