Use @layer

[firefoxic]

Have you considered replacing the wrapping of selectors in :where() with wrapping the entire library in the @layer normalize?

This would also avoid the specificity affect, but with the same simple selectors.

This also has the benefit of having low priority pseudo element selectors.
Those aren't valid in :where.
