Describe the bug

Hi Team,

when changing the flow direction in run time, with MirroredWhenRightToLeft property of font icon as true, font icon is not mirrored, not updated properly.
"MirroredWhenRightToLeft property works fine on initial loading alone.

<Grid Width="800" Height="200" BorderBrush="RoyalBlue" BorderThickness="3">
    <Grid.Resources>
        <Style TargetType="StackPanel">
            <Setter Property="HorizontalAlignment" Value="Center"/>
            <Setter Property="VerticalAlignment" Value="Center"/>
        </Style>
    </Grid.Resources>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <StackPanel Orientation="Vertical" FlowDirection="RightToLeft"   >
        <TextBlock Text="Right To Left - On Inital loading"/>
        <FontIcon Glyph="&#xE76C;"  Foreground="Black" FontSize="30" MirroredWhenRightToLeft="True" />
    </StackPanel>
    <StackPanel Orientation="Vertical" Grid.Column="1" x:Name="panel" >
        <TextBlock x:Name="textBlock" Text="Right To Left - Run time changing"/>
        <FontIcon Glyph="&#xE76C;" Foreground="Black" FontSize="30" MirroredWhenRightToLeft="True" />
    </StackPanel>
    <Button x:Name="myButton" Grid.Column="2" Click="myButton_Click">Change Flow Direction</Button>
</Grid>

Code Behind:

private void myButton_Click(object sender, RoutedEventArgs e)
{
    textBlock.Text = "Right To Left- Changed in Run time";
    panel.FlowDirection = FlowDirection.RightToLeft;
}

Steps to reproduce the bug

1.Provide font icon within a grid/stacklayout with MirroredWhenRightToLeft as true.
2,Modify the flow direction in run time.
3.Note icon is not mirrored.

Expected behavior

Icon should be mirrored based on the flow direction when the flow direction is changed at run time.
