2042063 - Implement sibling-count() and sibling-index() behind pref

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement)

Description

[Sajid Anwar [:sajidanwar]]

Tentative name is layout.css.tree-counting-functions.enabled. This bug will be for the primary implementation, with some follow ups to be made later (enabling/removing pref; probably caching-related things I'm out of my depth on; etc.).

Adding the dev-doc-needed flag, because once this basic imlementation lands, this should probably be documented at https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Experimental_features.
