TabIndex not working in ItemsControl.DataTemplate by default

I have an ItemsControl with n-TextBoxes which should be accessable by the Tab. Actually it is not working. I also tried to give each TextBox an own TabIndex (TabIndex="{Binding TabIndex}"; 1,2,…). Sadly as you can see in the preview it is not working.

<ItemsControl Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="5" Items="{Binding Path=LocalizedTexts}">
  <ItemsControl.ItemTemplate>
    <DataTemplate>
      <Grid>
        <Grid.ColumnDefinitions>
          <ColumnDefinition SharedSizeGroup="A" Width="Auto"/>
          <ColumnDefinition Width="20"/>
          <ColumnDefinition SharedSizeGroup="B" Width="Auto"/>
          <ColumnDefinition Width="20"/>
          <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        <TextBlock Grid.Column="0" Text="{Binding Locale}" VerticalAlignment="Center"/>
        <TextBlock Grid.Column="2" Text="{Binding OldText}" VerticalAlignment="Center"/>
        <TextBox Grid.Column="4" Text="{Binding Text, Mode=TwoWay}" IsTabStop="True" TabIndex="{Binding TabIndex}"/>
      </Grid>
    </DataTemplate>
  </ItemsControl.ItemTemplate>
</ItemsControl>

I think it is a feature, not a bug. You need to set KeyboardNavigation.TabNavigation property to Continue on ItemsPresenter.

<ItemsControl.Styles>
        <Style Selector="ItemsPresenter">
            <Setter Property="(KeyboardNavigation.TabNavigation)" Value="Continue" />
        </Style>
</ItemsControl.Styles>

Keeping this issue open for changing KeyboardNavigation.TabNavigation default value for list-like controls to match WPF defaults.

I think KeyboardNavigationMode.Once for ItemsControl is the same for WPF isn’t it? See https://stackoverflow.com/questions/1126838/tab-between-list-elements-wpf
