Memory leak when you access a web page that uses the "navigator.geolocation" object in Internet Explorer 9

Symptoms
Assume that you use Windows Internet Explorer 9 to open a web page that uses the navigator.geolocation object. When you refresh or leave the web page, a memory leak issue occurs.

For example, the memory leak issue occurs when you access a web page that contains the following code:
<!doctype>   <html>      <head>         <script language="javascript">            window.myexpando = window.navigator;             navigator.geolocation;         </script>      </head>   <body>      geolocation leak test   </body></html>
Cause
This issue occurs because Internet Explorer does not clean the references to the navigator.geolocation object correctly.
