I think this is more likely an issue with Ace, but thought worth checking in with you here first. Where I have: 

#element  {
    --margin: 1rem;
    margin: calc(var(--margin) * -1);
}

in my CSS, this is flagged as an error (Expected RBRACE at line 2 col 5). But as far as I can see this should be correct CSS (MDN web docs).

It is ace or more specifically csslint.
