Wicket 7 M1 different behaviour on

Hi Wicket users.

It looks like Wicket 7 treats all <button> without a type attribute as
submit buttons (6.15 does not)

Would it be possible revert this? or at least add a warning log message
when <button> is missing the attribute?

I think the code should control if the button submits the form.
(AjaxSubmitLink or AjaxLink) not the type attribute.

I've attached a quick start
