Re: [csswg-drafts] [selectors] Custom state pseudo class proposal (#4805)

#8094 points out that `:--foo` is also proposed for custom selectors, e.g. https://drafts.csswg.org/css-extensions/#custom-selectors has this example:

```css
@custom-selector :--heading {
  expansion: h1, h2, h3, h4, h5, h6;
}
```
