Per the current spec <https://drafts.csswg.org/css-lists/#creating-counters> counter values should percolate thru the element tree, same as other styles; it just has a funky "inherit from preceding element in the document" instead of the normal inheritance from its parent element.

That said, I know that Blink, at least, *actually* inherits thru the box tree and attempts to *emulate* inheriting thru the element tree (which results in some bugs, and also some bad perf stuff).

To get a page counter, the *intention* is that you do a counter-reset/increment in @page, then counter() will pick up the correct value based on what page it ends up on. (And presumably will change values in fixpos appearing on multiple pages? This isn't well-defined.)
