title: navigator.mediaDevices.enumerateDevices() only Returns Default Devices on Safari?
body: <p>On Firefox and Chrome,</p>
  
  <pre><code>navigator.mediaDevices.enumerateDevices()
  </code></pre>
  
  <p>...returns a list of all connected audio and video devices.</p>
  
  <p>But on desktop Safari, at least on my system, it's only returning the default devices.</p>
  
  <p>Is this expected behavior?</p>
