Bug 148870 – form.elements should reflect the element ordering after the HTML tree builder algorithm

• Component: Forms
• Status: RESOLVED FIXED

[Ryosuke Niwa]

When the HTML tree builder algorithm re-orders elements inside table, etc...
form.elements should be updated to reflect such re-ordering.

e.g. parsing the following HTML
<form id=form>
<table>
<tr>
<td><input type="radio" name="radio1" id="r1" value=1></td>
<td><input type="radio" name="radio2" id="r2" value=2></td>
<input type="radio"  name="radio0" id="r0" value=0>
</tr>
</table>
</form>

should put r0 at form.elements[0].

This bug was found by the newly added test:
LayoutTests/http/tests/w3c/html/semantics/forms/the-form-element/form-elements-nameditem-02.html

and both Firefox and Chrome pass this test.

"designated" seems rather vague.  How about m_parserSetForm or m_formSetByParser?

(In reply to comment #4)

I thought about that. I even called it something like that at first. But I backed away from that because it wasn't apparent to me that only the parser would be constructing HTMLFormControlElements with non-NULL HTMLFormElements. I'm pretty sure that that's the case *now*, but I didn't see anything that would prevent some other context from specifying an HTMLFormElement. That's why I went with a more general term.

But if you disagree with that line of thought, let me know and I'll change it.
