This doesn't seem clear to me. There is no omitted item between the commas, so the conditions in https://drafts.csswg.org/css-values/#comb-comma don't seem to apply.
> Something like: # allows an optional trailing comma
But why? Wouldn't allowing it at the end of a function or property value be enough?
Allowing a comma after `#` seems problematic if you have a grammar like `<ident># <ident>?`. If the value is `a, b, c`, does it mean that `a, b, c` is the `<ident>#` list and the final `<ident>?` is omitted? Or is `a, b` the `<ident>#` list, `,` the optional comma, and `c` the final `<ident>?`, i.e. a synonym of `a, b c`?
