Grid Star-Sizing does not work inside ListView

Describe the bug

When Star-Sizing is used inside of a Grid which is a child of ListView, the columns have no sizing and fill their minimum amount of space Steps to reproduce the bug

Steps to reproduce the behavior:

class Counter {
	string Name {
		get; set;
	}
	
	int Count {
		get; set;
	}
}

<ListView
        x:Name="itemsList"
        HorizontalContentAlignment="Stretch">
        <ListView.ItemTemplate>
            <DataTemplate>
                
                <Grid x:Name="itemGrid">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="4*"/>
                        <ColumnDefinition Width="1*"/>
                        <ColumnDefinition Width="2*"/>
                        <ColumnDefinition Width="1*"/>
                   
                    </Grid.ColumnDefinitions>


                    <TextBlock Text="{Binding Name}" Grid.Column="0"/>
                    <Button Content="+" Grid.Column="1"/>
                    <TextBlock Text="{Binding Count}" Grid.Column="2"/>
                    <Button Content="-" Grid.Column="3" />

                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>

Set the ListView.itemSource in code.

Expected behavior

Name is 4x larger than the buttons, which are half the size of the number Screenshots

@StephenLPeters Such a request was already made in the past (see the now closed issue https://github.com/microsoft/microsoft-ui-xaml/issues/1402) and back then @anawishnoff was not yet convinced of such a change. I suggest we re-open that issue if the team is open to discuss this again.

I’m fine with re-purposing this one or using the older, closed issue I didnt know about. Definitely think this needs to be rediscussed. If it really is different from WPF its something obvious to change to make everyone’s job easier moving to WinUI 3. Personally, I will then cleanup some xaml removing the customized styling.
