Inconsistent control styles in GridView rendering after applying windows 11 theme

Description

Inconsistent control styles in a GridView after applying the Windows 11 theme. The issue is affecting the rendering of data within the GridView, causing it to display incorrectly.

Reproduction Steps

XAML for GridView -

<ListView Name="lvUsers">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Name" Width="120" DisplayMemberBinding="{Binding Name}" />
            <GridViewColumn Header="Age" Width="50" DisplayMemberBinding="{Binding Age}" />
        </GridView>
    </ListView.View>
</ListView>

Code behind -

List<User> items = new List<User>();
items.Add(new User() { Name = "John Doe", Age = 42 });
items.Add(new User() { Name = "Jane Doe", Age = 39 });
items.Add(new User() { Name = "Sammy Doe", Age = 13 });
items.Add(new User() { Name = "Donna Doe", Age = 13 });

lvUsers.ItemsSource = items;

User class -

public class User
{
    public string Name { get; set; }

    public int Age { get; set; }
}

Expected behavior

The data in the GridView should be rendered correctly, maintaining a consistent appearance and style.

Actual behavior

After applying the Windows 11 theme, the GridView exhibits inconsistent control styles, leading to data rendering issues. This behavior deviates from the expected appearance.

Regression?

Please note that the DataGrid has very similar issues with both Headers and Content.

I also noted that content in the datagrid is aligned to Top/Left by default and requires a lot of work to adjust, which I traced down to two missing TemplateBindings in the style definition for DataGridCell.

I suggest changing the definition of the ContentPresenter in the ControlTemplate defined in Styles\DataGrid.Xaml

<Style x:Key="DefaultDataGridCellStyle" TargetType="{x:Type DataGridCell}">
...
<ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />

change to:

<ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                    HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                    VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
