Unexpected closing on ToolWindow when split the Pane

[Inseok]

Hi.
I think I found a bug(which you may aware) on ToolWindow.
And both Q1 2011 and Q2 2011 pre-beta have same issue.

Look at this code:

<Grid x:Name="LayoutRoot">
    <telerik:RadDocking>
        <telerik:RadSplitContainer InitialPosition="FloatingDockable">
            <telerik:RadPaneGroup>
                <telerik:RadPane Header="Pane 1">
                    <Grid Background="#52AB5454" />
                </telerik:RadPane>
                <telerik:RadPane Header="Pane 2">
                    <Grid Background="#524667B6" />
                </telerik:RadPane>
            </telerik:RadPaneGroup>
            <telerik:RadPaneGroup>
                <telerik:RadPane Header="Pane 3">
                    <Grid Background="#52AB5454" />
                </telerik:RadPane>
                <telerik:RadPane Header="Pane 4">
                    <Grid Background="#524667B6" />
                </telerik:RadPane>
            </telerik:RadPaneGroup>
        </telerik:RadSplitContainer>
    </telerik:RadDocking>
</Grid>

Just simple Floating panes. No more code. Nothing special.
But, when you drag&drop the PaneGroup left-side to the bottom of PaneGroup right-side to split vertically, then the ToolWindow will be closed immediately.
An interesting thing is, if you split the PaneGroups vertically(=switch the left and right), it's fine.

Could you test it and let me know what was the problem? Or some work-around for multiple floating panes?
