Xamarin.forms: [UWP] TitleView does not appear when used with TabbedView

[davidortinau]

Description

Not sure if it's related to #3834 , but I'm not seeing the TitleView I expect on UWP.

Steps to Reproduce

https://github.com/davidortinau/TheLittleThingsPlayground/blob/master/TheLittleThingsPlayground/Views/ThreeTwoPage.xaml#L17

<NavigationPage.TitleView>
        <StackLayout Orientation="Horizontal" VerticalOptions="Center" Spacing="10">
            <Image Source="{OnPlatform UWP=Assets/iconXamagon.png, Default=iconXamagon.png}">
                <Image.GestureRecognizers>
                    <TapGestureRecognizer
                        Command="{Binding TapCommand, Mode=OneWay}"
                        CommandParameter="https://www.xamarin.com"/>
                </Image.GestureRecognizers>
            </Image>
            <Label Text="3.2.0" FontSize="16" TextColor="Black" VerticalTextAlignment="Center" />
        </StackLayout>
    </NavigationPage.TitleView>

Expected Behavior

TitleView content appears in the blue bar title space.

Actual Behavior

It's empty.

Basic Information

• Version with issue: 3.4.0.1008975

Still happens on master. But our gallery page works

The TabbedPage implementation for TitleView on UWP was never implemented which is why it's not showing up here for UWP.
