[CSSWG][css-grid-3] Updated WD of CSS Grid L3

The CSS WG has published an updated Working Draft of the CSS Grid Layout 
Module Level 3:

     https://www.w3.org/TR/css-grid-3/

This module defines masonry layout (a type of 1-axis grid layout). Updates in 
this revision include defining “dense packing” for masonry, and clarifying 
baseline alignment and automatic track repetition.

There remain some major syntax questions open, which the Working Group is 
interested in broader feedback on:

   * Enabling masonry layout: what display name to use?
     https://github.com/w3c/csswg-drafts/issues/12022

     The CSSWG recently resolved to use a `display` value with the word
     `grid` in it, in order to preserve the idea that this is a type of
     grid layout; but we're looking for ideas on what that should be.

   * Interpreting row vs column in masonry layouts
     https://github.com/w3c/csswg-drafts/issues/12803

     This starts to get into questions of what’s obvious at first glance
     vs what’s obvious when you integrate it with the rest of CSS, and
     so far we don't have any obviously correct answers.

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

For the CSS WG,
