This is much needed. Use case:
We can use `ascent-override`, `descent-override`, `line-gap-override` and `size-adjust` in `@font-face` blocks to craft a fallback for a custom font. Or at least `size-adjust` (for width) and `ascent-overrode` for height. Safari supports `size-adjust` but none of the others. Which makes the fallback worse than if it supported nothing. So I need to test for `ascent-override` support and the only robust solution is to use JavaScript like
```js
if ('ascentOverride' in new FontFace(1,1)) {...}
```
