Re: [svgwg] Clarify whether `var()` (custom properties) are allowed in SVG presentation attributes, and how they are parsed/resolved (#1031)

@longsonr @emilio does Firefox also parse these substitution function values like `var()` or `env()` as given in the spec (using [parse grammer](https://drafts.csswg.org/css-syntax/#parse-grammar)), if yes when the parsed values are being substituted?
