operator== recursive

[sake402]

Given the following static operator==

public static bool operator ==(HttpMethod left, HttpMethod right) =>
    left is null || right is null ?
         ReferenceEquals(left, right)
        : left.Equals(right);

The left is null is compiled as though it were left == null which causes the operator to invoke itself

                op_Equality: function (left, right) {
                    return System.Net.Http.HttpMethod.op_Equality(left, null) || System.Net.Http.HttpMethod.op_Equality(right, null) ? H5.referenceEquals(left, right) : left.equalsT(right);
                },

Changing the c# code to this unblock me for now

   public static bool operator ==(HttpMethod left, HttpMethod right) =>
       ReferenceEquals(left, null) || ReferenceEquals(right, null) ?
            ReferenceEquals(left, right)
           : left.Equals(right);
