Test case

When pressing enter in a text field, the first non-disabled submit button should be the submitter. However, in webkit and not in conformance with the spec, buttons with the "hidden" attribute are ignored.
See attached test case, works according to spec in Chromium & Gecko
Spec: https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#implicit-submission
