Re: [csswg-drafts] [css-fonts-4] Add syntax for <font-src-list> (#9462)

`invalid` is not a valid `<font-src>` but `invalid, url(font.woff2)` is a valid `<font-src-list>`, therefore `[<font-src> | <any-component-excluding-comma>]#` would be more accurate than `<font-src>#`.

However, `<media-query-list>`, `<forgiving-selector-list>`, `<block-contents>` and its equivalent but more restrictive productions, are not expanded.
