Unable to get property 'dispatchEvent' of undefined or null reference error in IE11
We are seeing a JavaScript error when we select an Option in a Select control with a ASP Postback on IE11 via keyboard input.
<%@ Page Language="C#" AutoEventWireup="true" Inherits="System.Web.UI.Page" %>
<script runat="server">
void Page_Load(object sender, EventArgs e)
{
decorator.DecoratedControls = FormDecoratorDecoratedControls.Select;
}
</script>

<body>
<form id="DialogForm" runat="server">
<telerik:RadScriptManager runat="server" />
<telerik:RadAjaxManager runat="server" />
<telerik:RadFormDecorator ID="decorator" runat="server" DecorationZoneID="Panel1" EnableEmbeddedSkins="false" RenderMode="Lightweight" />
<telerik:RadAjaxPanel ID="Panel1" runat="server">
<asp:DropDownList ID="DD1" runat="server" AutoPostBack="true">
<asp:ListItem Text="[Select]" Value="" />
<asp:ListItem Text="T1" Value="1" />
<asp:ListItem Text="T2" Value="2" />
</asp:DropDownList>
<asp:Button runat="server" Text="Refresh" />
</telerik:RadAjaxPanel>
</form>
</body>
</html>
Reproduce by clicking the DropDown control, and then pressing 'T', and then clicking on a blank section of the page.
