Description

The number of SearchHandler toolbar item (normally should only one) will increase by one at the bottom when the software starts, and then increase by two each time navigating from other pages

This only occurs when Microsoft.Maui.Controls is 9.0.70

Steps to Reproduce

1. Upgrade Microsoft.Maui.Controls to 9.0.70

2. Add a SearchHandler to a ContentPage

<ContentPage>
    <Shell.SearchHandler>
        <handlers:MainSearchHandler SearchBoxVisibility="Collapsible" />
    </Shell.SearchHandler>
</ContentPage>

MainSearchHandler is a derived class of SearchHandler

internal class MainSearchHandler : SearchHandler { }

3. Launch the app on Android
