It seems that the font information of a style isn't serialized in the viewstate

Step to reproduce

<%@ Page language="c#" %>

  <script language="C#" runat="server">

    void Page_Load(object sender, System.EventArgs e) 
    {
        if (!IsPostBack) {
                        myLbl.Text="ok";
                        Style myStyle = new Style();
                myStyle.ForeColor = System.Drawing.Color.Red;
                myStyle.Font.Bold=true;
                        myLbl.ApplyStyle(myStyle);
                }
    } 
  </script>
<html>
 <head>

 </head>
 <body>
   <form runat="server">

                                <asp:Label id="myLbl"
runat="server"></asp:Label>
                                <asp:Button id="myButton"
runat="server"></asp:Button>
   </form>
 </body>
</html>
