Re: [csswg-drafts] [css-nesting] How to resolve nested CSS with pseudo elements in the parent (#7433) from Guillaume via GitHub on 2022-07-25 (public-css-archive@w3.org from July 2022)

I was checking if `&div` is valid and found this example in [3. Nesting Selector: the & selector](https://drafts.csswg.org/css-nesting-1/#nest-selector):

> For example, `&div` is a valid nesting selector, meaning "whatever the parent rules matches, but only if it’s also a `<div>` element".

If I understand this correctly, `div { &div {} }` would be (silly but) valid and you cannot desugar it with `:is(div)div`. I am not sure to understand why `&` compounded with `<type-selector>` would be valid, though. It may be an actual bug in the spec.
