The metrics from the font are OS2 table are ySubscriptYOffset, ySuperscriptYOffset. They're ignored, and our testing notes have "Firefox uses 0.34em and -0.2em, Safari 0.333em and -0.2005em"
Another possibility is to incorporate this into https://github.com/w3c/csswg-drafts/issues/4792 - you could have
```css
@font-face {
font-family: ...
superscript-position: auto;
subscript-position: from-font;
}
```
where `auto` is current behaviour, `from-font` is strictly from the font OS2 table, or an absoute value could be specified.
I can see you're working through a lot of font metrics issues at the moment, which is great - I think many of them could be solved by implementing #4792
(earlier comment on this issue by me was posted too soon due to fat fingers - I deleted it)
