navigator.cookieEnabled does not work on ie11 or Edge,

I tried this code and when I execute it it gives me true even when I have disabled the cookies in EDge, it does not mark me error or anything, and I need that result to validate the action of a send. I hope you can help me, Thanks!

function myFunction() {
    var x = "Cookies enabled: " + navigator.cookieEnabled;
    document.getElementById("demo").innerHTML = x;
}
