title: Polymer fails to load in iOS10 but not iOS9
body: <p>I have an Aurelia app running in phonegap and it works fine on ios9+ but on ios10+ it fails to load Polymer.</p>
  
  <p>When the Aurelia polymer plugin checks to see if Polymer is on the window object it is null.</p>
  
  <p>I am loading webcomponents-lite.js and it is initializing properly.</p>
  
  <p>Not sure where to look
