title: Jquery prop only working on first 'mouseover' event
body: <p>I am using a bootstrap tooltip to show the title of a map marker on mouseover. I am using 'prop' to set the title.</p>
  
  <p>The problem is that the tooltip title attribute remains set as the first marker you mouseover.</p>
  
  <pre><code>markers[id].addListener('mouseover', function () {
      console.log(markers[id].title);
      /* get marker pixel position */
      var proj = overlay.getProjection();
      var pos = markers[id].getPosition();
      var p = proj.fromLatLngToContainerPixel(pos);
      /* show tooltip */
      $("#tooltip").css("left", p.x + "px").css("top", (p.y + 20) + "px").prop('title', markers[id].title).tooltip('show');
  });
  </code></pre>
