Enabling Fast renders - crashes RadialMenu with CenterButtonView

[Vadim Koystinen]

Fast renderers cause RadialMenu to crash with either Image or Label in center button view....

AppActivity: Forms.SetFlags("FastRenderers_Experimental");

 <radialMenu:SfRadialMenu Grid.Column="3" Grid.Row="1"  TranslationY="-25"  Margin="0,-30,0,-40" CenterButtonRadius="30"  RimRadius="100" RimColor="Black" CenterButtonBackgroundColor="DarkGray"  CenterButtonBorderColor="Transparent" CenterButtonBorderThickness="3">

                <radialMenu:SfRadialMenu.CenterButtonView>

                    <Label Text="Menu" VerticalOptions="Center"   />

                    <!--<Image x:Name="centerButtonImage" HeightRequest="22" WidthRequest="22"  Source="ic_dots_vertical_white_24dp.png" Aspect="AspectFill" />-->

                </radialMenu:SfRadialMenu.CenterButtonView>               

            </radialMenu:SfRadialMenu>
