Actually, that’s a very good point, but not for the reason you posted it. This is not possible AT ALL if ::page() is a pseudoelement, as elements cannot be nested in pseudoelements: “the pseudo-element must appear after the compound selector that represents the subjects of the selector” [1]
However, it doesn’t make sense for it to be a pseudo-class either, for the reason I mentioned in my previous message. Therefore, it follows that the only possible solution is nesting if we want this kind of flexibility.
Unless we define the pseudo-class as "where the element starts" and use the existing :page() pseudos [2] for styling the rest of the fragments. But that’s really clumsy.
