What is clobbering window.page on my Galaxy S3?

Are you using some browsers window.pagefor something?

I ask because my web application mysteriously failed on my Galaxy S3 phone running Android 4.3. Research has shown that something knocked down my global variable pagewith HTMLBodyElement. It works fine on my Android 4.3 virtual machine. Here's the POC:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8"/>
    <script type="text/javascript">
      window.page = 0;
      window.addEventListener("load", start, false);
      function start()
      {
          if (isNaN(window.page))
              alert(window.page);
          setTimeout(function(){alert(window.page);}, 5000);
      }
    </script>
  </head>
  <body>
    <table>
      <tr>
        <td>This is some text that is long enough to wrap around.</td>
        <td>This is some text that is long enough to wrap around.</td>
        <td>This is some text that is long enough to wrap around.</td>
      </tr>
    </table>
  </body>
</html>

Expected behavior: after 5 seconds the message box says 0(the value assigned to window.page).

Observed behavior: message box after 5 seconds [object HTMLBodyElement]
