ListView ViewCell content disappears when the application enters the foreground

Description

A simple page consists only a ListView, which has a ViewCell as DataTemplate.

When the app on iOS (whether device or simulator) goes to the background and then back to the foreground, the content of the CellViews disappears. Only empty cells remain.

Steps to Reproduce

1. Create a New .NET MAUI App from the template
2. Replace the content of MainPage.xaml

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="ListTest.MainPage">

    <ContentPage.ToolbarItems>

    </ContentPage.ToolbarItems>

    <ListView>

        <ListView.ItemsSource>
            <x:Array Type="{x:Type x:String}">
                <x:String>One</x:String>
                <x:String>Two</x:String>
                <x:String>Three</x:String>
            </x:Array>
        </ListView.ItemsSource>

        <ListView.ItemTemplate>
            <DataTemplate x:DataType="x:String">
                <ViewCell>
                    <Grid
                        ColumnDefinitions="80,*">
                        <Button Text="{Binding .}"/>
                    </Grid>
                </ViewCell>
            </DataTemplate>
        </ListView.ItemTemplate>

    </ListView>

</ContentPage>

1. Run the app on iOS Simulator 16.0. The app shows a list with three lines of buttons.
2. Send the app to the background. Do not close the app!
3. Pull the app back to the foreground

What should happen:

The app looks like before.

What happens instead:

The three lines are still visible, but the buttons disappear.

This worked with Xamarin! So it’s a big issue when migrating to .NET MAUI.

To the MAUI team, I am sorry but this is not a “move to backlog” issue. This is critical. I was shocked to see this issue was created back in November with no response since.

1. DIsplaying lists is a very common app function.
2. Sending apps to the background is a very common user action.

One might recommend that we could use CollectionView, but frankly, that also has a whole separate set of issues that made me switch back to ListView.

I was struggling with this issue and CachingStrategy="RecycleElement" fixed it on the XAML of the list view
