dbaron has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-shadow-parts][css-nesting] is & allowed after ::part() ==
I don't think it's clear whether [the `&` selector](https://drafts.csswg.org/css-nesting-1/#nest-selector) is allowed after [the `::part()` pseudo-element](https://drafts.csswg.org/css-shadow-parts-1/#part).  At least, I read what I think are the relevant specs and I couldn't find any wording that gives me a clear answer.

For example, is the following CSS:

```css
:hover {
  ::part(mypart)& {
    text-decoration: underline;
  }
}
```

equivalent to:

```css
::part(mypart):hover {
  text-decoration: underline;
}
```

or is it invalid?
