[iOS] Clicking on search suggestions fails to navigate to detail page correctly

[risukun]

Description

I was hitting a bug in my app that clicking on a search suggestion using NavigationBar/SearchBar/custom SearchHandler not actually navigating to the item I was clicking on with iOS 26.2 and MAUI 10. During my investigation I found that it repros in this sample app as well:
https://github.com/dotnet/maui-samples/tree/main/10.0/Fundamentals/Shell/Xaminals

Steps to Reproduce

1. Open the following public MAUI Sample App:
   https://github.com/dotnet/maui-samples/tree/main/10.0/Fundamentals/Shell/Xaminals
2. Connect to Mac device with xcode 26.2 and deploy to iPhone 17 Pro 26.2 simulator.
3. Put focus on the search box:

4. Type 'b' (note that search dropdown position is wrong, see Issue [iOS] SearchHandler suggestions list does not follow the search bar upward movement on iPhone, creating a layout gap #32930)

5. Click on 'Bengal' => Issue 1
   Expected: Navigates to Bengal cat detail page.
   Actual: No navigation happens.

6. Click on 'Bengal' entry on the main list => actually navigates from the items list (but not from the search suggestion list)

7. Click back button => Issue 2
   Expected: navigates back to list
   Actual: navigates to an empty page

8. Click back button one more time, actually navigates back
