Description

Parsing a style rule with a linear-gradient, and then writing the same rule back to css causes the angle to get removed.

Steps to Reproduce

class Program
    {
        static void Main(string[] args)
        {
            var parser = new CssParser();
            var styleSheet = parser.ParseStyleSheet(".bg { background-image: linear-gradient(to right, #FF866E 0, #F15A24 0); }");
            var css = styleSheet.ToCss();
            Console.WriteLine(css);
            // Outputs
            // .bg { background-image: linear-gradient(rgba(255, 134, 110, 1) 0, rgba(241, 90, 36, 1) 0) }
        }
    }
