I get different hashcode on the same action that assigend from same virtual method

class Program
{
    public virtual void VirtualMethod() { }

    public void NonVirtualMethod() { }


    static void Main(string[] args)
    {
        Program p = new Program();
        Action d1 = p.VirtualMethod;
        Action d2 = p.VirtualMethod;

        Action d3 = p.NonVirtualMethod;
        Action d4 = p.NonVirtualMethod;
        
        Console.WriteLine("d1.GetHashCode() == d2.GetHashCode() {0}", d1.GetHashCode() == d2.GetHashCode());
        Console.WriteLine("d3.GetHashCode() == d4.GetHashCode() {0}", d3.GetHashCode() == d4.GetHashCode());
    }
}

d1.GetHashCode() == d2.GetHashCode() False
d3.GetHashCode() == d4.GetHashCode() True

    @parjong Have you submitted a separate issue for the new test case?

    Good point. @parjong Could you please add the test case for this if there is not one already?

    @jkotas I already did. Please take a look at dotnet/coreclr#13531.
