Searchhandler dissapears or does not appear at all

Legends commented 9 months ago

Description

Android only (Works on Windows)

When I add a <Shell.TitleView> with content to my AppShell.xaml the search handler of each page does not appear anymore. Except for the CatsPage.xaml page where the searchhandler is shown at application start, but the Shell.TitleView is not shown. When i switch through the tabs in the tabbar you can see, that none of the pages show the searchhandler anymore, but all of them show the Shell.TitleView . Now when I switch back to the CatsPage.xaml, the searchhandler is gone here too and the Shell.TitleView is visible now.

The gif starts with the CatsPage and a visible search box: Screenrecorder-2024-02-05-19-32-53-277-ezgif com-optimize

When I remove <Shell.TitleView> it works again, each page shows its seachhandler.

Expected: The search handler to be visible on every page Dogs,Cats,Monkeys,Bears,Elephants. Each of them has a searchhandler.

Steps to Reproduce

Add following xaml to AppShell.xaml:

<Shell.TitleView>
    <HorizontalStackLayout HorizontalOptions="CenterAndExpand"
                           VerticalOptions="CenterAndExpand">
        <Label Text="I am Shell.TitleView"
               TextColor="Green"
               HorizontalOptions="Center"
               VerticalOptions="Center"
               Padding="0,10,10,0" />
        <Image Source="info.png"
               WidthRequest="20"
               Margin="0,0,0,-10"
               HorizontalOptions="Center"
               VerticalOptions="Center" />
    </HorizontalStackLayout>
</Shell.TitleView>
