Child rendering behaviour mismatched after upgrading Xamarin.Forms (>4.0) in FlexLayout

Hi All,

I have a simple sample with the layout structure of FlexLayout which has more number of Grid. Each Grid has two children that are

1. Grid with Label as a child

2. Custom View (TouchView) which is inherited from View.

   <FlexLayout HorizontalOptions="Start" 
                                   VerticalOptions="Center" 
                                   Direction="Row" 
                                   Wrap="Wrap" 
                                   BindableLayout.ItemsSource="{Binding ChildItems}"
                                   JustifyContent="Start" 
                                   AlignContent="Start" 
                                   AlignItems="Start">
   
               <FlexLayout.BindableLayout.ItemTemplate>
                   <DataTemplate>
                       <Grid>
                           <Grid BackgroundColor="Aqua">
                               <Label TextColor="Black" Text="{Binding}"/>
                           </Grid>
                           <local:TouchView/>
                       </Grid>
                   </DataTemplate>
               </FlexLayout.BindableLayout.ItemTemplate>
   
           </FlexLayout>
   

Here TouchView represents like

public class TouchView:View
    {

    }

This FlexLayout wrap its child element correctly up to the Xamarin.Forms version of 3.6.0.539721

But after 4.0.0.425677 , it rendered be like in below

Note : Issue only with Android platform.

@Xamariners please check this and update us with possible solution. Actually it blocks our development cycle. Taking this a high priority and provide a solution ASAP.

I have attached the sample in both lower and higher version of Xamarin.Forms.
