PDTree drag and drop with custom NodeTemplate doesn't have a PlaceHolder?

[rickers1]

I am using

<PDDragContext>
     <PDTree //...>
           <NodeTemplate>
                // My template followed by ...
               <MudIconButton ButtonType="ButtonType.Button"
                                            Size="MudBlazor.Size.Small"
                                            Icon="@Icons.Material.Filled.Delete"
                                            Color="Color.Error"
                                            OnClick="() => ItemDelete(PDTreeCtx)">
                </MudIconButton>
           </NodeTemplate>
     </PDTree>
</PDDragContext>

It works fine except that when I drag an item the placeholder shows as the whole PDTree not just the PDTreeNode I am dragging. If I remove the MudIconButton from the NodeTemplate it works as expected with the placeholder being only the PDTreeNode I am dragging.

Is there something I am missing here in the setup?
