dijit.form.Button click sensitivity when submitting

[remmons]

When using a dojo button, there is a sensitivity to where you can click the button when using type="submit".

The following are two situations that I've identified when clicking a dojo button along the very bottom of the button and the behavior isn't desirable. (Clicking in a 'normal' place on the button works as expected)

Nothing happens here when clicking the bottom of the button:

<button dojoType="dijit.form.Button" type="submit">Submit Button</button>

The javascript is fired, however the submit is not when clicking on the bottom.

<button dojoType="dijit.form.Button" type="submit" onclick="alert('test');">Submit Button</button>

This can be seen on the following page using the "Plain Submit" button at the bottom of the page.

I've reproduced this in Releases 1.32 and 1.4 using Firefox 3.5 and IE 7 & 8.

Right, dup of #6880 I think.
