[csswg-drafts] [css-regions-1] `flow-into` and `flow-from` should exclude all CSS-wide keywords (#9160)

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

== [css-regions-1] `flow-into` and `flow-from` should exclude all CSS-wide keywords ==
[`flow-into`](https://drafts.csswg.org/css-regions-1/#propdef-flow-into) is defined with `none | <ident> [element | content]?` and `<ident>` excludes `none`, `inherit`, `default`, `auto`, `initial`.

[`flow-from`](https://drafts.csswg.org/css-regions-1/#flow-from) is defined with `<ident> | none` and does not exclude CSS-wide keywords.

I suspect `<ident>` should be `<custom-ident>` in both properties.

---

**The more important underlying question I have is:** should a CSS parser give priority to the grammar of CSS-wide keywords, property substitution values, or of the property value definition?
