RadListBox Height 100% not working in Mozilla Firefox

Hi,
We have nested Rad Splitter and RadPane scenario. and in one place we have a RadListBox  in RadPane with 100% height and it take all the space in Internet Explorer. But is only show 3 rows height in Mozilla FireFox. 
         <telerik:RadPane ID="rp" runat="server" Width="100%" MinHeight="200" Scrolling="None" BackColor="Red">
                                                            <telerik:RadListBox
                                                                runat="server" ID="lst"
                                                                Height="100%" Width="250px"
                                                                AllowReorder="true" OnClientDeleted="lstMeasuresItemDeleted"
                                                                EnableDragAndDrop="true" SelectionMode="Multiple">
                                                                <Items>                                                                                                                                       
                                                                    <telerik:RadListBoxItem Value="1" Text="A"/>
                                                                    <telerik:RadListBoxItem Value="2" Text="B"/>
                                                                    <telerik:RadListBoxItem Value="3" Text="C"/>
                                                                </Items>   
                                                            </telerik:RadListBox>
                                                        </telerik:RadPane>
Is there anyway to fix it for Mozilla Firefox to have 100% heigh in radpane.
Thanks
