title: Google map infowindow is offset by 2px
body: <p>I am using the standard <code>infoWindow</code> dialog. However there is a 2px offset where the speech bubble and arrow meet:</p>
  
  <p><img src="https://i.stack.imgur.com/UFZVQ.png" alt="google map offset"></p>
  
  <p>Any reason this might be happening?</p>
  
  <p>This is a sample of the code I'm using:</p>
  
  <pre><code>var infoWindow = new google.maps.InfoWindow({});
  
  google.maps.event.addListener(marker, 'click', function() {
      var contentString = '&lt;p&gt;Content Here&lt;/p&gt;';
      infoWindow.setContent(contentString);
      infoWindow.open(map, marker);
  });
  </code></pre>
