title: Safari PDF controls missing PDF is rendered in iFrame
body: <p>Anyone know why the PDF controls normally available when displaying a PDF in Safari would be missing when displayed in an <code>iframe</code>? Neither the "hover" controls or the extnded contextual menu is available. Safari reognized it as a PDF because the contextual menu includes the word PDF in the Open commands, ie. "Open PDF in new Window"</p>
  
  <p>Opening a PDF into an empty browser works fine. The built in controls in Chrome and Firefox are there as well and work fine. </p>
  
  <p>I am serving the PDFs using a very simple web page with an <code>iframe</code> inside a <code>div</code>.</p>
  
  <p>I could be wrong but thought that they were there when I first started this project but I just noticed today that they are missing. Without them, PDF drawings cannot be zoomed in and out rendering them useless as PDFs.</p>
