[whatwg] fieldset disabled and first legend

The current specification for the fieldset element's disabled attribute
is the following:
"The disabled attribute, when specified, causes all the form control
descendants of the fieldset element, excluding those that are
descendants of the fieldset element's first legend element child, if
any, to be disabled."
First of all, "form control descendants" isn't really clear considering
there is no real definition of "form control" in the specification
AFAIK. Why not using "listed elements" instead? which would correspond
to all elements returned by .elements.
This is very interesting to have the elements inside the first legend to
not be disabled. I guess the idea is to have a checkbox enabling some
options. For example, "advanced options" in a configuration.
However, the specification seems to miss one edge case. What if a
fieldset has been disabled because it is inside a disabled fieldset?
Depending on how you read the current specification, you can consider
that the elements inside the first legend of the second fieldset should
be disabled or not. My opinion is, those elements should be disabled and
that's the current Gecko's behavior (current nightly and next beta).
It would be good to add something mentioning this edge case.
