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:

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!
