title: Submit button not focused even though tabindex is properly set
body: <p>I have defined tab index for the input fields in a form. When tabbing through the input fields the submit button is never getting the focus, some other input fields in a different form on the page gets the focus. Those are all having tab indexes higher than 3. How come?</p>
  
  <pre><code>&lt;form action="subscription.php" name="subscribe" method="post"  onsubmit="return isValidEmailAndEqual()"&gt;
  &lt;p id="formlabel"&gt;E-mail&lt;/p&gt; &lt;input type="text" name="email1" tabindex=1&gt;
  
  &lt;br/&gt;
  &lt;p id="formlabel"&gt;Repeat e-mail&lt;/p&gt; &lt;input type="text" name="email2" tabindex=2&gt; &lt;br/&gt;
  &lt;input id="inputsubmit" type="submit" value="Subscribe" tabindex=3&gt;
  &lt;/form&gt;
