Research direction

Start with the provided WPF DataGrid XAML reproduction on Windows 11 with .NET 6 and WPF-UI 2.0.3. Investigate the column-resizing path and the reported DataGridColumnFloatingHeader type mismatch when CanUserResizeColumns is false. Done means resizing no longer throws that exception under the supplied configuration.
