Re: [csswg-drafts] @font-face overrides for superscript/subscript metrics (#5518)

Apologies for not making the call yesterday, it was at 2am local time.

All four? We have [three currently](https://drafts.csswg.org/css-fonts-4/#font-metrics-override-desc) : `ascent-override`, `descent-override` and `line-gap-override`; and resolved to add two more, making five.

> The [grammar](https://drafts.csswg.org/css-fonts-4/#font-metrics-override-desc) for these descriptors today is `normal | <percentage>`, where `normal` means "do whatever you're doing today."

Currently for these three, [the spec says](https://drafts.csswg.org/css-fonts-4/#font-metrics-override-desc)

> When the descriptor value is normal, the corresponding metric value is obtained from the font file directly. 

So with `normal | <percentage> | from-font` what is the definition of 'normal'? And if is is "do whatever magic you are currently doing, maybe get if from the font, maybe not" isn't that a classic case for `auto`?
