User is allowed to redefine @counter-style rules predefined by user-agent, except if the rules are: Except for "decimal, disc, square, circle, disclosure-open, and disclosure-closed" according to https://w3c.github.io/csswg-drafts/css-counter-styles/#the-counter-style-rule. We currently just avoid 'decimal' and 'disc' from being redefined.
