BarManager doesn't close popups when it's used inside ViewToContractAdapter as a separate add-in

Hi

We are trying to move to a multi-process ui hosting framework where plug-ins are hosted in their own process and the top-level visual component is not a Window, but a ViewToContractAdapter from the Addins namespace:

defined in System.Windows.Presentation.dll

namespace System.AddIn.Pipeline
{
    // Summary:
    //     System.AddIn.Pipeline.FrameworkElementAdapters is used by Windows Presentation
    //     Foundation (WPF) add-ins to convert between a System.Windows.FrameworkElement
    //     and an System.AddIn.Contract.INativeHandleContract.
    public static class FrameworkElementAdapters
    {
        // Summary:
        //     Returns a System.Windows.FrameworkElement that has been converted from an
        //     System.AddIn.Contract.INativeHandleContract.
        //
        // Parameters:
        //   nativeHandleContract:
        //     The System.AddIn.Contract.INativeHandleContract that was passed across the
        //     isolation boundary between the host application and the add-in.
        //
        // Returns:
        //     A System.Windows.FrameworkElement that will be displayed from either the
        //     host application or add-in, depending on the direction in which the UI is
        //     passed between the two.
        [SecurityCritical]
        public static FrameworkElement ContractToViewAdapter(INativeHandleContract nativeHandleContract);
        //
        // Summary:
        //     Returns an System.AddIn.Contract.INativeHandleContract that has been converted
        //     from a System.Windows.FrameworkElement.
        //
        // Parameters:
        //   root:
        //     The System.Windows.FrameworkElement to be passed across the isolation boundary
        //     between the host application and the add-in.
        //
        // Returns:
        //     An System.AddIn.Contract.INativeHandleContract that is passed from either
        //     the host application or the add-in, depending on the direction in which the
        //     UI is passed between the two.
        //
        // Exceptions:
        //   System.InvalidOperationException:
        //     root is not the root element of a tree of elements.
        [SecurityCritical]
        public static INativeHandleContract ViewToContractAdapter(FrameworkElement root);
    }
}

After switching to this, I am running into problems.  So far I noticed 2 below.    Do you assume that the top level control is a window anywhere in your code?

1. I cannot close the the popups that hold BarSubItems.  Once opened. they stay opened.
2. I get this exception when showing/hiding TabLayoutPanel of the DevExpress DockLayoutManager
