Document belongs to another FlowDocumentScrollViewer already exception when using scrollbar

Question

I have a ListView of FlowDocuments:

            <ListView ItemsSource="{Binding Messages}">
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <FlowDocumentScrollViewer Document="{Binding Message}"                                                       
                                                      ScrollViewer.VerticalScrollBarVisibility="Disabled"
                                                      HorizontalContentAlignment="Left" Margin="-10,0,0,0"
                                                      VerticalContentAlignment="Top"></FlowDocumentScrollViewer>

                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>

And whenever I use the scrollbar that gets shown after a certain amount of items in the listview to scroll back up, an External Code Exception gets thrown:

I clicked "Show External Code" to reveal the details.
