Re: [csswg-drafts] [css-fonts-4] [varfont] Supported variation font axes and font features are not discoverable from Brian Smith via GitHub on 2017-06-01 (public-css-archive@w3.org from June 2017)

Consider the following CSS:

```css
@supports (font-feature-settings: "subs" 1) {
  sub, sup { vertical-align: baseline; font-size: 100% }
  sub { 
    font-feature-settings: "subs" 1
  }
  sup {
    font-feature-settings: "sups" 1
  }
}
```

Basically, I want to use have the font position/size the superscripts and subscripts if it supports those features. Otherwise, I want to use the default positioning/sizing. However, this doesn't work, because the browser does support `font-feature-settings: "sups" 1` but the font itself is missing the feature.
