Cannot submit dynamic form when the form go to the same URL

Question

Hi,
I am using Safari 5.1 (7534.50). I am having problem on dynamic form submission.
When I click on the button 1 on the following form, it will open a page in a new window.
After that, if I push the button 2, the form cannot be submit and it won't open a new page.
If I push the button 1 again, the form cannot be submit again either.
<form target="_blank" action="http://www.domain.com" method="get" name="prForm">
<input value="0" name="test">
</form>
<a href="javascript:submitForm(1);">Submit Button 1 </a>
<a href="javascript:submitForm(2);">Submit Button 2</a>
<script type="text/javascript" language="javascript">
function submitForm(val) {
    var pf = document.prForm;
    pf['test'].value = val;
    pf.submit();
</script>
This behaviour has been considered as a bug in Google Chrome and has currently been fixed.
I wonder if Apple will fix the same bug in the future?
