title: How to set title in window popup when URL points to a PDF file?
body: <p>In javascript I create a URL which points to a PDF and open a new window. The window title contains the URL which I would like to hide from the user. </p>
  
  <p>I tried the following suggestion <a href="https://stackoverflow.com/questions/7501424/set-title-in-the-window-popup">Set title in the window popup</a> but this doesn't seem to work for PDFs.</p>
  
  <p>Is there a way to solve this problem?</p>
