[whatwg] [CSSWG][css-lists-3] Updated WD of CSS Lists Level 3

[fantasai]

The CSS WG has published an updated Working Draft of the CSS Lists Module Level 3:
     https://www.w3.org/TR/css-lists-3/

This module contains CSS features related to list markers and counters: 
styling them, positioning them, and manipulating their value.

This update contains a major clean-up of the “Automatic Numbering with 
Counters” section, including fixing various sync errors against CSS2.1. It 
should now be usable as a reference for implementation.

[See also announcement on the previous update, which was a rewrite of the 
list-styling section: 
https://lists.w3.org/Archives/Public/www-style/2019Apr/0024.html ]

Major areas of work left include:
   - Improving definitions for how list markers are positioned and
       how they impact layout. (This is largely undefined at the moment.)
   - Figuring out how to best support ol[reversed] list numbering for HTML.

i18n-related open issues include:
   - https://github.com/w3c/csswg-drafts/issues/4209 [syntax for marker-side]
   - https://github.com/w3c/csswg-drafts/issues/4202 ['direction' on markers]

a11y-related open issues include:
   - https://github.com/w3c/csswg-drafts/issues/4201

HTML-related open issues include:
   - https://github.com/w3c/csswg-drafts/issues/4181 reversed list decrement
   - https://github.com/w3c/csswg-drafts/issues/4211 reversed list start value

Please review the draft, and send any comments to <www-style at w3.org>, prefixed 
with [css-lists-3] (as I did on this message) or (preferably) file them in the 
GitHub repository at
   https://github.com/w3c/csswg-drafts/issues
