[whatwg] :enabled and :disabled pseudo-classes should apply on fieldset elements

[Mounir Lamouri]

Hi,

The current state of the specifications do not mention fieldset elements
for the :enabled and :disabled pseudo-classes but fieldset can be
disabled so I guess it might be convenient to have these pseudo-classes
applied to them.

Opera applies :disabled and :enabled to fieldset elements and Mozilla
might do the same.

Thanks,
