TabView.TabItemTemplate throws exception in only 1 pattern, is this the intended behavior?

[shinta0806]

When using TabItemTemplate, an exception may occur depending on the description method.

description method	OK / NG
inner content, no header	NG
inner content, with header	OK
inline content, no header	OK
inline content, with header	OK

<TabView TabItemsSource="{x:Bind ViewModel.TabItems, Mode=TwoWay}" Width="500" Height="200" >

            <!-- NG 
            <TabView.TabItemTemplate>
                <DataTemplate >
                    <TabViewItem >
                        <TextBlock Text="ct" />
                    </TabViewItem>
                </DataTemplate>
            </TabView.TabItemTemplate>
            -->

            <!-- OK
            <TabView.TabItemTemplate>
                <DataTemplate >
                    <TabViewItem Header="hd" >
                        <TextBlock Text="ct" />
                    </TabViewItem>
                </DataTemplate>
            </TabView.TabItemTemplate>
            -->

            <!-- OK
            <TabView.TabItemTemplate>
                <DataTemplate >
                    <TabViewItem Content="ct" >
                    </TabViewItem>
                </DataTemplate>
            </TabView.TabItemTemplate>
            -->

            <!-- OK
            <TabView.TabItemTemplate>
                <DataTemplate >
                    <TabViewItem Header="hd" Content="ct" >
                    </TabViewItem>
                </DataTemplate>
            </TabView.TabItemTemplate>
            -->

</TabView>

Is this the intended behavior?
