ListView CanReorderItems not working with custom ItemsPanel

[HO-COOH]

Describe the bug

It seems that using any custom panel as ItemsPanel for ListView, it can no longer reorder items. Built-in StackPanel works fine.

Steps to reproduce the bug

1. Create a new WinUI3 project, install the CommunityToolkit.WinUI.Controls package
2. Use this xaml

<Window ... 
    xmlns:controls="using:CommunityToolkit.WinUI.UI.Controls">
    <ListView CanReorderItems="True" AllowDrop="True">
        <ListView.ItemsPanel>
            <ItemsPanelTemplate>
                <controls:WrapPanel Orientation="Horizontal"/>
            </ItemsPanelTemplate>
        </ListView.ItemsPanel>

        <x:String>Item1</x:String>
        <x:String>Item2</x:String>
        <x:String>Item3</x:String>
    </ListView>

3. Try drag and reorder the items. It only shows a red stop sign.

Expected behavior

Should be able to reorder the items.

Pretty sure this is intentional. toolkit wrap panels themselves has to include drag and drop support

Maybe that's true. Can you share an example to implement that with custom panel?

This is by design. The panels need to impliment some interfaces to participate in drag and drop. StackPanel impliments IInsertionPanel. https://learn.microsoft.com/en-us/uwp/api/windows.ui.xaml.controls.iinsertionpanel?view=winrt-22621. Not sure if that is sufficient.
