Nit: I'm curious why this change is needed. It looks inconsistent that we have
'using WebCore::Member' and 'using WebCore::Result' but can't have 'using
WebCore::Handle'.

I agree. I'll add a FIXME(oilpan) about this. The issue is that in some Mac core
framework files that are used here there is another definition of Handle. The
compiler complaints that 'using WebCore::Handle' is conflicting with another
type that is already available. This is not a problem for the other ones.

Makes sense.

         if (data->type == CSSRuleSourceData::STYLE_RULE)
             target.append(data);
         else if (data->type == CSSRuleSourceData::MEDIA_RULE)
