+Subject: [PATCH] Amend syntax of `if()`, drop value of `<if-condition>`
+
+For `if()`, parsing fails on `;?`.
+
+For `<if-condition>`, the problem is that the spec extends the Value Definition
+Syntax with a new construct that is not yet supported by the CSS parser.
+
+Both problems have been fixed in CSSTree already, but a new version still needs
+to be released. See tracking issue in:
+https://github.com/w3c/webref/issues/1378
