As an update to our intent here. as posted by Xiaocheng earlier, we're planning to ship the size-adjust descriptor <https://drafts.csswg.org/css-fonts-5/#size-adjust-desc>. On Mon Feb 22 16:50:28 PST 2021 Xiaocheng Hu xiaochengh@chromium.org wrote: Hi webkit-dev,
This is a request for WebKit's position on a new descriptor 'advance-override' of the CSS @font-face rule. This is a new feature that the CSSWG just added into CSS Fonts Level 5 for reducing layout shifting caused by web fonts. Chrome has already implemented it in M90 behind a flag.
Explainer: https://gist.github.com/xiaochengh/3aae8a97d1b0388c8e701819b63e2c49 Spec: https://drafts.csswg.org/css-fonts-5/#font-metrics-override-desc May I assume https://github.com/w3c/csswg-drafts/pull/5991, authored by Myles, as a positive signal? Thank you!
