[webkit-dev] Request for position: CSS @font-face descriptor advance-override

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!
