title: Customize Infowindow : move arrow to the left not working on first click
body: <p>I'm using the "5 ways to customize the Google Maps Infowindow"
  ( code here : <a href="https://codepen.io/Marnoto/pen/xboPmG" rel="nofollow noreferrer">https://codepen.io/Marnoto/pen/xboPmG</a> )</p>
  
  <p>When clicking for the first time on the marker, the window opens, but the arrow don't move to the left (this appens not all the time, but very often). </p>
  
  <p>Starting the second click, it's positioning correctly, as written in the JS :</p>
  
  <pre><code>// Moves the arrow 76px to the left margin.
  iwBackground.children(':nth-child(3)').attr('style', function(i,s){ return s + 'left: 76px !important;'});
  </code></pre>
  
  <p>Here is a pic of the problem
  <a href="https://i.stack.imgur.com/e56Rm.jpg" rel="nofollow noreferrer">capture</a></p>
  
  <p>And here is a pic of how it works when the style property is correctly applied
  <a href="https://i.stack.imgur.com/SOrVM.jpg" rel="nofollow noreferrer">capture 2</a></p>
  
  <p>Is there a way to fix this ??</p>
  
  <p>Thank you!</p>
