[css-overflow-3] Updated Working Draft of the CSS Overflow L3

The CSS Working Group has published an updated Working Draft of the CSS Overflow Module Level 3.

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

This module contains the features of CSS relating to scrollable overflow handling in visual media. This level is focused on completing a precise specification for the existing overflow features, including the 'overflow' property and its longhands; 'line-clamp', its longhands, and its legacy pre-standard syntax; and the 'text-overflow' property. A few additional features introduced in support of the CSS Containment Module (see https://www.w3.org/TR/css-contain-2/) are also defined: 'overflow: clip' and the 'overflow-clip-margin' property.

The primary changes since the previous Working Draft are:
    * Moving in the 'scroll-behavior' and 'scrollbar-gutter' properties from CSSOM-VIEW and css-overflow-4, respectively.
    * Adding box-edge keywords to 'overflow-clip-margin'.
    * Tightening up requirements around incorporating margins, padding, and zero-area boxes into the scrollable overflow area.

See the Changes section for further details:

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

For the CSS WG,
