Q1803 Why won't the form submit() method work?

The submit method fails if there is a submit button named submit, for example

this does not work:
<a href="javascript:document.forms.testForm.submit()">submit Form</a>
<form name=testForm>
<input type=submit name=submit>
</form>

this works:
<a href="javascript:document.forms.testForm.submit()">submit Form</a>
<form name=testForm>
<input type=submit name=submitButton>
</form>
