[Bug] Frame IsClippedToBound broken on IOS somewhere after 4.6.0.800

[ish-1313]

Description

I have the following code (related part)

    <Grid Padding="0" ColumnSpacing="2" Margin="0,5,0,5" HorizontalOptions="Fill" x:Name="Item">
                           <Grid.ColumnDefinitions>
                               <ColumnDefinition Width="{StaticResource PetImageWidth}"/>
                               <ColumnDefinition Width="*" />
                           </Grid.ColumnDefinitions>
                           <Grid.RowDefinitions>
                               <RowDefinition Height="{StaticResource PetImageHeight}" />
                           </Grid.RowDefinitions>

                           <Frame Grid.Row="0" Grid.Column="0"  IsClippedToBounds="True" CornerRadius="50"   Padding="0" 
                                                  HorizontalOptions="Fill" VerticalOptions="Fill">
                               <Image   Source="{Binding BindingImageSource}" Style="{StaticResource PetImageStyle}"  />
                           </Frame>

which makes rounded image. after upgrading to 4.7.0.968 (same with 4.7.0.1080) I found , that on IOS I am having squared image (on Android ok ).
reverting back to 4.6.0.800 , got rounded image

• Version with issue:
  at least 4.7.0.968 and 4.7.0.1080
• Last known good version:
  4.6.0.800
• IDE:
  Visual studio for Mac 8.6.5.23
  Xamarin.Mac 6.18.0.23 (d16-6 / 088c73638)

Screenshots

between screenshots only Xamarin.forms nuget package was updated from 4.6.0.800 to 4.7.0.968

Could be the same as #11091
In this case, will be fixed by #11129

it seems that for quick workaround the easiest way will be to use imagebutton instead frame+image

<!--
  <Frame Grid.Row="0" Grid.Column="0"  IsClippedToBounds="True" CornerRadius="50"   Padding="0" 
                                 HorizontalOptions="Fill" VerticalOptions="Fill">
      <Image   Source="{Binding BindingImageSource}" Style="{StaticResource PetImageStyle}"  />
    </Frame>
      -->
    <ImageButton Grid.Row="0" Grid.Column="0" CornerRadius="50" WidthRequest="100" HeightRequest="100"
                       Source="{Binding BindingImageSource}" IsEnabled="False" Aspect="AspectFill" />

result
