Grouped tab - search handler issue

[Legends]

Description

The following code is from the .net maui samples repo.
Issue: dotnet/maui-samples#424
Link to sample "Xaminals" is attached.

The app uses Shell navigation.
Every page in this example has its own search handler configuration.

The issue occurs only for the grouped tab "Domestic" that has two tabs "Dogs" and "Cats".

Issue: The first page to load is "Cats", now when I switch to tab "Dogs" and search for dogs, I get cats!

When I put a breakpoint inside the OnQueryChanged method, I can see that the search handler is actually the
cats' search handler from the previous tab "Cats".

 <FlyoutItem Route="animals"
             FlyoutDisplayOptions="AsMultipleItems">
     <Tab Title="Domestic"
          Route="domestic"
          Icon="paw.png">

         <ShellContent Route="cats"
                       Style="{StaticResource DomesticShell}"
                       Title="Cats"
                       Icon="cat.png"
                       ContentTemplate="{DataTemplate views:CatsPage}" />

         <ShellContent Route="dogs"
                       x:Name="dogsItem"
                       Style="{StaticResource DomesticShell}"
                       Title="Dogs"
                       Icon="dog.png"
                       ContentTemplate="{DataTemplate views:DogsPage}" />
     </Tab>

Steps to Reproduce

1.) Run the app => VS F5
2.) Switch to Dogs page.
3.) Search for "Ben"
4.) Search result shows cats instead of dogs.

It can also happen that you go to another animal catergory and go back to dogs and it suddenly it works.
Or you come back to cats and and your search shows dogs.

Hello @Legends
I faced issues with SearchHandler, hence I changed to use Shell.TitleView which gave me more control over SearchBar. Please check if it works for you.
