[selectors] :where definition missing link to Specificity definition #6932
Description
Quoting from https://drafts.csswg.org/selectors-4/#zero-matches (emphasis added):
The Specificity-adjustment pseudo-class,
:where(), is a functional pseudo-class with the same syntax and functionality as:is(). Unlike:is(), neither the:where()pseudo-class, nor any of its arguments, contribute to the specificity of the selector—its specificity is always zero.
None of these mentions of specificity are currently hyperlinked. At least one of them should link to https://drafts.csswg.org/selectors-4/#specificity , i.e. the definition of specificity in this same spec.
