Current Behavior

Applying the TouchBehavior to a ContentView (at least on Windows) - when the hover state is complete the view retains the configured HoveredBackgroundColor and does not restore the original ContentView color. I've tried on a few controls, seems to be ContentView specific so far.

Expected Behavior

When the hover completes the original state of the view should be restored.

Steps To Reproduce

1. Open and run the attached repro.
2. Mouse over the image at the top.
3. Mouse away from the image at the top. Notice the result is this red background color that does not go away:

            <!-- Only change to the template empty project code is this ContentView with the TouchBehavior added around the Image -->
            <ContentView>
                <ContentView.Behaviors>
                    <toolkit:TouchBehavior
                        HoveredBackgroundColor="#88ff0000"/>
                </ContentView.Behaviors>
                <Image
                    Source="dotnet_bot.png"
                    HeightRequest="185"
                    Aspect="AspectFit"
                    SemanticProperties.Description="dot net bot in a race car number eight" />
            </ContentView>

As a workaround, you can set the DefaultBackgroundColor value so that it changes back to the expected value, eg DefaultBackgroundColor="Transparent"
