The issue is resolved by replacing the code snippet below. To correct we must loop through all the validators for a control, then we should decide whether it has to marked with the error class. After this, your code will work as expected.

Replace the loop

 for (var i in Page_Validators) {
    try {
        var control =
        document.getElementById(Page_Validators[i].controltovalidate);
        if (!Page_Validators[i].isvalid) {
            control.className = "error";
        } else {
            control.className = "";
        }
    } catch (e) { }
}

with the below code

 for (var j in Page_Validators) {
        try {
            var control =
                        document.getElementById(Page_Validators[j].controltovalidate);
            var IsError = false;
            for (var i in control.Validators) {

                if (!control.Validators[i].isvalid) {
                    IsError = true;
                }
            }

            if (IsError)
                control.className = "error";
            else
                control.className = "";
        } catch (e) { }
    }

I just ran it and this is working excellently :) Try this solution!
