ToolWindow overlaps taskbar if UseHostedAutoHidePopups is set to false

Hello,

in our application we are hosting WinForms within the ToolWindows, so we needed to set UseHostedAutoHidePopups="False".

If you run the sample below and if you click on the hidden ToolWindow in the right corner and then move the MainWindow down, you can observe that the ToolWindow overlaps the TaskBar.

How can we fix this behaviour?

<Window x:Class="SampleToolWindowBugForActipro.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:docking="http://schemas.actiprosoftware.com/winfx/xaml/docking" 
        Title="MainWindow" Height="350" Width="525">
    
    <docking:DockSite UseHostedAutoHidePopups="False">
            
        <docking:Workspace>
            <docking:TabbedMdiHost>
                <docking:TabbedMdiContainer>
                    <docking:DocumentWindow Title="DocumentWindow" />
                </docking:TabbedMdiContainer>
            </docking:TabbedMdiHost>
        </docking:Workspace>

        <docking:DockSite.AutoHideRightContainers>
            <docking:ToolWindowContainer>
                <docking:ToolWindow Title="ToolWindow" />
            </docking:ToolWindowContainer>
        </docking:DockSite.AutoHideRightContainers>

    </docking:DockSite>
</Window>

Thanks in advance.
