Re: [csswg-drafts] [css-values-5] Trailing comma in `attr()` (#8387)

But @tabatkins, custom properties can also be defined with `attr()`, `env()`, `paint()`, `random-item()`, `mix()`, which are all defined with `, <declaration-value>?` or `, <whole-value>`.

These [tests](https://github.com/web-platform-tests/wpt/blame/c2d015181a4956b2f91061595ec7da93823ec3ec/css/css-env/env-parsing.html#L12-L13) for `env()` allows a trailing comma.

What am I missing?
