Switch control not shows thumb color properly in the Windows when initially its state is off.

[divyesh008]

Description

I have used the Switch control in my page like this:

 <HorizontalStackLayout Margin="{OnPlatform Android='0,15,0,0', iOS='0,25,0,20'}" Spacing="20">
    <Switch
        HorizontalOptions="Start"
        IsToggled="{Binding CorrectOnSite}"
        OnColor="{StaticResource MidGray}"
        ThumbColor="{StaticResource WhiteSmoke}" />
    <Label
        Style="{StaticResource DisplayFieldFieldTextStyle}"
        Text="Corrected onsite"
        VerticalOptions="Center"
        VerticalTextAlignment="Center" />
</HorizontalStackLayout>

When I run the app in the Windows device, it shows output like this:

As you can see in the recording it does not show ThumbColor at all when its off initially, if I toggle the switch from off to on and vice versa than only it shows ThumbColor.

Steps to Reproduce

1. Add a Switch control and set IsToggled to False initially.
2. Set OnColor and ThumbColor values.
3. Run the app in Windows.
4. Notice the Switch control appearance.
