     * XXXgijs: we would like to enable this, but we can't right now.
     * This is because Gecko uses a number of custom pseudoclasses,
     * and stylelint assumes that for `:unknown-pseudoclass(foo)`,
     * `foo` should be a known type.
     * This is tedious but workable for things like `-moz-locale-dir` where
     * the set of acceptable values (ltr/rtl) is small.
     * However, for tree cells, the set of values is unlimited (ie
     * user-defined, based on atoms sent by the JS tree view APIs).
     * There does not appear to be a way to exempt the contents of these
     * unknown pseudoclasses, and as a result, this rule is not
     * usable for us. The 'type' only includes the contents of the
     * pseudoclass, not the pseudo itself, so we can't filter based on the
     * pseudoclass either.
     * Ideally, we would either create an option to the builtin rule
     * in stylelint itself, or mimic the rule but exempt these, or
     * add parser support for our custom pseudoclasses.
     *
     * For now, we just disable this rule.
