  // ------ The snippet below is almost identical to the official one however
  // ------ we substitute in widgetUrl instead of a statically defined one.
  // ------ In addition, it has been found that the window.onload event is unreliable
  // ------ in some browsers (specifically on mobile), where it may never fire.  
  // ------ We have replaced waiting on window.onload with simply executing the script loader.
  // ------ As we are inside of Meteor.startup, this should be ok.
