CollectionView not scrolling inside a StackLayout or without setting HeightRequest

Description

If the items inside an ObservableCollection are too many for a CollectionView to display, they can’t be scrolled if the CollectionView is inside a StackLayout.

Steps to Reproduce

1. Create a new MAUI project;
2. Add a StackLayout and inside a CollectionView;
3. Bind the ItemSource of the CollectionView to a property in the MVVM with many items;
4. Voilà, you now can’t scroll the CollectionView. But if you change the StackLayout into a Grid, or if you add a HeightRequest to the CollectionView (voilà again) you now can scroll it.

Did you find any workaround?

The only way to scroll them is set the HeightRequest property to the CollectionView or change the StackLayout into a Grid.

Thats the buggy code: <StackLayout> <CollectionView ItemsSource="{Binding Monkeys}"> <CollectionView.ItemTemplate> <DataTemplate> <Label Text="{Binding Title}" /> </DataTemplate> </CollectionView.ItemTemplate> </CollectionView> </StackLayout>

But if you add the HeightRequest property to the CollectionView it works fine: <StackLayout> <CollectionView ItemsSource="{Binding Monkeys}" HeightRequest="200" > <CollectionView.ItemTemplate> <DataTemplate> <Label Text="{Binding Title}" /> </DataTemplate> </CollectionView.ItemTemplate> </CollectionView> </StackLayout>

And if you add change the StackLayout into a Grid it still works fine: <Grid> <CollectionView ItemsSource="{Binding Monkeys}"> <CollectionView.ItemTemplate> <DataTemplate> <Label Text="{Binding Title}" /> </DataTemplate> </CollectionView.ItemTemplate> </CollectionView> </Grid>
