title: Chrome - add filename and download name to base64 encoded PDF in iframe viewer
body: <p>I am encoding a PDF as base64 data, and am displaying this data in an iFrame as such in my react app:</p>
  
  <pre><code>&lt;iframe
    src={`data:application/pdf;base64,${
      this.props..encodedPdf
    }`}
  /&gt;
  </code></pre>
  
  <p>This renders nicely, but because of the B64 encoded data, the PDF has this at the top:
  <a href="https://i.stack.imgur.com/7sAYd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7sAYd.png" alt="enter image description here"></a></p>
  
  <p>Additionally when I download it, it's saved as <code>download.pdf</code></p>
  
  <p>Is there any way to change the title or the download name?</p>
