Description
Describe the bug
GridSplitter does not update Grid column sizes when dragged horizontally in WPF UI. Is this expected behavior or a style override?
To Reproduce
<Grid Margin="0,6,6,6">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition Width="auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Border
Grid.Column="0"
</Border>
<GridSplitter Grid.Column="1" Width="1" />
<Border
Grid.Column="2"
</Border>
</Grid>
Expected behavior
Expected behavior:
The GridSplitter should retain its default WPF behavior and correctly resize adjacent Grid columns when dragged horizontally.

Research direction
Reproduce the issue using the provided Grid and GridSplitter sample on Windows 11 with .NET 10 and WPF-UI 4.3.0. Compare the result with default WPF behavior and inspect the WPF-UI styling or control resources that apply to GridSplitter; done means adjacent columns resize horizontally as expected or the behavior is confirmed and documented.
