title: cannot read property 'getusermedia' of undefined over https
body: <p>I have a react application that should record audio from microphone and send it to a backend.
  The microphone input is implemented with navigator.mediaDevices.getUserMedia. The page runs perfectly over localhost and from other devices in my wifi network(for that I had to start my react app with https).
  But when I test it with this website: <a href="http://appsimulator.net/webapp/?frame=apple_iphone_6_v" rel="noreferrer">http://appsimulator.net/webapp/?frame=apple_iphone_6_v</a>, I get the following error: TypeError: Cannot read property 'getUserMedia' of undefined.
  I don't know why it is not possible to test the app over this site.</p>
