NavigationView Header gets cut off in Minimal PaneDisplayMode when back and paneToggle buttons are hidden #10489
Description
Describe the bug
When the NavigationView enters Minimal PaneDisplayMode and both IsBackButtonVisible="Collapsed" and IsPaneToggleButtonVisible="False" are set, the Header gets cut off instead of being properly aligned.
Steps to reproduce the bug
-
Create a new WinUI 3 application.
-
Replace the content of MainWindow.xaml with the following code:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TitleBar
Height="{Binding ElementName=navView, Path=CompactPaneLength}"
IsBackButtonVisible="True"
IsPaneToggleButtonVisible="True" />
<NavigationView
x:Name="navView"
Grid.Row="1"
Header="Test"
IsBackButtonVisible="Collapsed"
IsPaneToggleButtonVisible="False">
<Button x:Name="myButton" Click="myButton_Click" />
</NavigationView>
</Grid>
-
Run the application.
-
Resize the window so that the NavigationView switches to Minimal PaneDisplayMode.
-
Observe that the Header gets cut off instead of being properly aligned.
Expected behavior
The NavigationView header should remain fully visible and properly aligned when the control enters Minimal PaneDisplayMode, even when IsBackButtonVisible="Collapsed" and IsPaneToggleButtonVisible="False" are set.
