Test case

WPT: form.action does not return document.url when unset (part of https://wpt.live/html/dom/reflection-forms.html)

Test: https://wpt.live/html/dom/reflection-forms.html
Spec: https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#dom-fs-action

From the spec: "The action IDL attribute must reflect the content attribute of the same name, except that on getting, when the content attribute is missing or its value is the empty string, the element's node document's URL must be returned instead".

HTMLFormElement::action() and HTMLFormControlElement::formAction() are now identical, except for the attribute retrieved.

Is there a good place to share the code?  Not necessary to land the patch; just noticed white reviewing.

Not at the minute. Darin and I are discussing how to potentially cover more Reflection cases in https://bugs.webkit.org/show_bug.cgi?id=213227, which, depending on what we do, could cover this as well.
