[css-properties-values-api] initial-value for * with arbitrary substitution values

[cdoublev]

If I understand the spec correctly, initial-value does not require to be validated when syntax is *.

But in Chrome, given the CSS rules below:

• the first rule is valid: initial-value: var(1) is discarded
• the second rule is invalid

@property --p1 {
  inherits: false;
  syntax: "*";
  initial-value: green;
  initial-value: var(1);
}
@property --p2 {
  inherits: false;
  syntax: "*";
  initial-value: green;
  initial-value: var(--initial);
}

I am completely confused by the parse result in Chrome. Anyway, should initial-value be invalid when it includes an arbitrary substitution value?

Hm, the spec is indeed unclear here. I prefer Chrome's behavior - validating the initial-value as normal for an untyped custom property. The spec just needs its conditions to be slightly rephrased to match.
