Steps to reproduce the problem:
Attempt to print page numbers with a 'position: fixed' element with 'content' set to a css counter.

See code snippet at https://developer.mozilla.org/en-US/Apps/Progressive/Responsive/Media_types$revision/1227799#Action_Printing_a_document

Print the page in Firefox and Chrome.

What is the expected behavior?
The counter should increment on every page, since the fixed element shows on every page. That gives you the page number.

On Firefox this works.

What went wrong?
The counter never increments. Every page is marked as "Page 1".

Did this work before? No 

Does this work in other browsers? Yes

Chrome version: 61.0.3163.100  Channel: stable
OS Version: OS X 10.12.6
Flash Version: 

The code snippet on MDN has been there since the first rev added in 2005, and has been referenced on other places when people try to print page numbers, like [1]

I am not entirely sure if this is a spec'd behavior. CSS asks fixed positioned element to appear on every page on printing media [2], which Chrome does do it, but the CSS counter spec [3] does not mention whether or not counter should increment whenever the element is rendered.

I have thus decided to try my luck here too see if I can get this clarified.
