The RadWindow width and height are not persisted when the control has been minimized before a PostBack (or navigation to another page).
Steps to reproduce:
1. Run the code below.
2. Click the "Open" Button
3. Minimize RadWindow
5. Click the "PostBack" button
6. Maximize RadWindow
Result: The restored RadWindow has wrong size
<telerik:RadButton ID="Btn1" runat="server" Text="Open" AutoPostBack="false" OnClientClicked="openFirst"></telerik:RadButton>

<telerik:RadButton runat="server" ID="RadButton1" Text="Postback" AutoPostBack="true" />
