[csswg-drafts] [css-values-5] Should an arbitrary substitution nested within another be accepted in context? (#10337)

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

== [css-values-5] Should an arbitrary substitution nested within another be accepted in context? ==
```css
@page { size: env(safe-area-inset-top, attr(size length)) }
```

Is `size` declared with a valid value?

`var(--custom, var(1))` must be invalid in any property value: the basic syntax of `var(1)` is checked, but should its validity in the context be checked?
