Yes. Prototype's selector doesn't ensure proper order of elements
(with complex selectors) and only does so coincidentally when
`document.querySelectorAll` is being used.

It should be possible to do so with `Form.getElements` which relies on
`getElementsByTagName("*")`
$(someForm).getElements().findAll(function(el){
return el.descendantOf(someElement);
});
