RSRP-469411: Incorrect "redundant parentheses" message in rare corner cases

Consider this code:

        public static void Main() {
            int x = 0, y = 0, z = 0, w = 0;
            System.Console.WriteLine("{0}{1}", (x < y), z > (w + 1));
        }

In this case, Rider tells that the parentheses around (x < y) are redundant. That's not the case, because code becomes invalid. See the screenshots:




It looks like Rider's parser also has problems with this code: it sometimes consider the code as valid and sometimes as invalid.
