Why VisualState "PointerOver" fails to work on ContentDialog ?

[sigmarsson]

Having this style beneath, which is working impeccable on any user control but PointerOver state does not work when employed the user control the a ContentDialog. Could that be ?

        <Style x:Key="ThemeButtonStyle" TargetType="uc:ThemeButton">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="uc:ThemeButton">
                        <RelativePanel x:Name="RelativePanel" Background="{TemplateBinding Background}">
                            <SymbolIcon x:Name="Symbol" Symbol="{TemplateBinding Symbol}" RelativePanel.AlignTopWithPanel="True" Margin="5">
                                <SymbolIcon.RenderTransform>
                                    <ScaleTransform CenterX="0" CenterY="0" ScaleX="0.5" ScaleY="0.5"/>
                                </SymbolIcon.RenderTransform>
                            </SymbolIcon>
                            <TextBlock Text="{TemplateBinding Content}" RelativePanel.AlignBottomWithPanel="True" Margin="5" FontSize="10"/>
