The CSS parsing code uses a strategy of consuming trailing whitespace, we should
probably be consistent and do the same for calc instead of adding this opposite
strategy.

+    {
+        consumeWhitespace();
+        return consume();
+    }
+
     // The returned range doesn't include the brackets
     CSSParserTokenRange consumeBlock();
