[webkit-dev] Request for position on @font-face descriptors ascent/descent/line-gap-override to override font metrics

[Xiaocheng Hu]

Hi webkit-dev,

I'd like to request an official position on @font-face descriptors
`ascent-override`, `descent-override` and `line-gap-override` for
overriding the default font metrics.

Explainer:
https://gist.github.com/xiaochengh/da1fa52648d6184fd8022d7134c168c1
Spec: https://drafts.csswg.org/css-fonts-4/#font-metrics-override-desc
Chromestatus: https://www.chromestatus.com/feature/5651198621253632

Other information:

These descriptors are newly added into CSS Fonts Level [1], following a
recent resolution [2].
Chromium has already implemented them in M86 behind a flag [3].
