title: Highlight/mouseover broken with Polygons in KMZ file Google Maps v3
body: <p>I'm trying to get the highlight/hover/mouseover styles working for a KMZ Placemark using Google Maps v3. When I open the KMZ file with Google Earth, the appropriate area when hovered will change to the highlightPlacemark style as intended. But when I load this KMZ onto a Google Map object, the style never changes.</p>
  
  <p>Here is what the styles look like:</p>
  
  <pre><code>&lt;Style id="highlightPlacemark"&gt;
      &lt;LineStyle&gt;
          &lt;color&gt;ff000000&lt;/color&gt;
      &lt;/LineStyle&gt;
      &lt;PolyStyle&gt;
          &lt;color&gt;a60000ff&lt;/color&gt;
      &lt;/PolyStyle&gt;
  &lt;/Style&gt;
  &lt;StyleMap id="exampleStyleMap"&gt;
      &lt;Pair&gt;
          &lt;key&gt;normal&lt;/key&gt;
          &lt;styleUrl&gt;#normalPlacemark&lt;/styleUrl&gt;
      &lt;/Pair&gt;
      &lt;Pair&gt;
          &lt;key&gt;highlight&lt;/key&gt;
          &lt;styleUrl&gt;#highlightPlacemark&lt;/styleUrl&gt;
      &lt;/Pair&gt;
  &lt;/StyleMap&gt;
  &lt;Style id="normalPlacemark"&gt;
      &lt;LineStyle&gt;
          &lt;color&gt;ff000000&lt;/color&gt;
      &lt;/LineStyle&gt;
      &lt;PolyStyle&gt;
          &lt;color&gt;a6ffffff&lt;/color&gt;
      &lt;/PolyStyle&gt;
  &lt;/Style&gt;
  </code></pre>
  
  <p>Here is what the Placemark looks like:</p>
  
  <pre><code>&lt;Placemark id="1"&gt;
      &lt;name&gt;Test&lt;/name&gt;
      &lt;Snippet maxLines="0"&gt;&lt;/Snippet&gt;
      &lt;styleUrl&gt;#exampleStyleMap&lt;/styleUrl&gt;
      &lt;Polygon&gt;
          &lt;extrude&gt;1&lt;/extrude&gt;
          &lt;tessellate&gt;1&lt;/tessellate&gt;
          &lt;outerBoundaryIs&gt;
              &lt;LinearRing&gt;
                  &lt;coordinates&gt;
                      ...lots of coordinates here...
                  &lt;/coordinates&gt;
              &lt;/LinearRing&gt;
          &lt;/outerBoundaryIs&gt;
      &lt;/Polygon&gt;
  &lt;/Placemark&gt;
  </code></pre>
  
  <p>Does this feature only work in Google Earth or is there a workaround to make it work in Google Maps v3?
  The only way I can think of is to create individual Polygon objects, and providing the coordinates to them individually. This allows you to use the mouseover event of the Polygon class. I would rather have all my Polygons in 1 single file though...</p>
  
  <p>Thanks in advance!</p>
