Description

When the first ShellContent in a TabBar has its IsVisible property set to false and then navigation occurs to another tab, the TabBar displays incorrect tabs (shows wrong tab titles/content).

Steps to Reproduce

1. Create a MAUI Shell application with a TabBar containing 7 tabs
2. On the first tab (Home/MainPage), set this.IsVisible = false in code-behind
3. Navigate to another tab (e.g., Page5) using Shell.Current.GoToAsync($"///{nameof(Page5)}")
4. Observe that the TabBar now displays incorrect tabs on Android
5. Navigate to another tab (e.g., Page51) using await Shell.Current.GoToAsync($"{nameof(Page51)}");
6. On iPhone Page51 doesn't appear. It shows only after tapping three dots (more tabs button) ... !?!?
