Why do you remove it?

[sof, 2013/12/10 08:35:29]

FormAssociatedElement::form() implements it.

[tkent, 2013/12/10 08:49:49]

form() IDL function uses HTMLElement::formOwner() instead of
FormAssociatedElement::form().  This looks a behavior change.

[sof, 2013/12/10 08:53:57]

Which IDL function/attribute "form" are you referring to?

[sof, 2013/12/10 08:56:41]

(Please also notice the virtualForm() overloads of the FormAssociatedElement
subclasses.)

[tkent, 2013/12/10 08:59:01]

Oops, it's not an IDL function.  I meant 'form' IDL attributes of button,
fieldset, input, keygen,  output, select, and textarea.

[sof, 2013/12/10 09:03:01]

Same functionality/behavior is provided, see
HTMLFormControlElement::virtualForm()

[tkent, 2013/12/10 09:07:50]

ok, I understand.

I expect only literal renaming for a CL of which description says it renames
something. Such changes need explanation.
