title: Google Map directionsRenderer using polyline miss some routes in waypoints
body: <p>I'm using the Google Map API.  I want to show the dotted routes in map.  If I add polylineDotted object to google.maps.DirectionsRenderer, it will miss some path on the map.  Between point A and point B route is missing(please check my <a href="http://jsfiddle.net/ntcc2vaw/79/" rel="nofollow noreferrer">jsfiddle</a>).</p>
  
  <p>I had tried not using polylineDotted, it will be OK.</p>
  
  <pre><code>var polylineDotted = new google.maps.Polyline({
      strokeColor: '#9966ff',
      strokeOpacity: 0,
      fillOpacity: 0,
      icons: [{
          icon: lineSymbol,
          offset: '0',
          repeat: '10px'
      }],
  });
  </code></pre>

  <p>My wish features must in could:</p>
  
  <ol>
  <li>List item</li>
  <li>Color #9966ff</li>
  <li>Dotted routes</li>
  <li>Multiple waypoints</li>
  </ol>
