Research direction
Reproduce the issue with the ui:DataGrid using MVVM ItemsSource binding and CanUserReorderColumns="True" on Windows with .NET Framework 4.8 and WPF-UI 2.0.3. Start by tracing the column-header drag path and the TargetType mismatch involving DataGridColumnFloatingHeader; done means columns can be reordered without the InvalidOperationException.
