I want to confirm that syntactically valid variable declarations and
references in an @supports condition won't cause the condition to fail.
Specifically:
@supports (color: var(a)) { ... succeeds ... } @supports (color: 2px var(a)) { ... succeeds ... } @supports (color: var(a) ! important) { ... succeeds ... } @supports (var-a: abc) { ... succeeds ... } @supports (var-a: var(a)) { ... succeeds ... } @supports (color: var(a,)) { ... fails ... } @supports (color: var(a) ! something) { ... fails ... } @supports (var-a: abc;) { ... fails ... } @supports (var-a:) { ... fails ... }
