Component are saved in viewstate even if EnableViewState=false on Controls (not
on the page)

Reproducible: Always

Steps to Reproduce:
1.try this aspx :
<%@ Page Language="C#" Inherits="testweb.Test" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
    <title>Test</title>
</head>
<body>
    <form id="form1" runat="server">
        <asp:Label id="lbl1" runat="server"
EnableViewState="false"></asp:Label>
        <asp:Button  runat="server" Text="PostBack me"></asp:Button>
    </form>
</body>
</html>

and aspx.cs

sing System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace testweb
{

    public partial class Test : System.Web.UI.Page
    {
        protected Label lbl1;

        protected override void OnLoad (System.EventArgs e)
        {
            Console.WriteLine("Viewstate enabled for lbl1
?"+lbl1.EnableViewState);

            if (!IsPostBack) {
                Console.WriteLine("Not postback");
                lbl1.Text="coucou";
            }
            else {
                Console.WriteLine("postback");
                Console.WriteLine("lbl1.Text "+lbl1.Text);
            }
        }

    }
}

2. Compile it and run xsp
3. Click on PostBack me
Actual Results:  
Viewstate enabled for lbl1 ?False
Not postback
Viewstate enabled for lbl1 ?False
postback
lbl1.Text coucou

Expected Results:  
The label is saved in the viewstate... it should not because EnableViewState is
set to false

This bug breaks one of our project... 
that use this behaviour...

and we often set EnableViewState=false when we don't need it to reduce page
size!

I think it's a major broken feature!

I reproduce it since mono 2.2 (2.2.x -> 2.4.x) not tested on svn
