C# 当值通过转换器以应用按钮Bg时，VisualStateManager不工作

我通过转换器应用按钮的背景色。起初，它被正确地应用，但在它被悬停或按下后，背景色将永远消失，不再回来

期望的行为

默认状态

盘旋

悬停状态后

我的问题

悬停状态结束时，橙色背景不再显示

实施

按钮使用

<Button Content="Continue" Style="{StaticResource ButtonAnyColorStyle}">
    <Button.Background>
        <SolidColorBrush Color="{Binding something, Converter={StaticResource PanelBgColorConverter}, Mode=TwoWay}"  />
    </Button.Background>
</Button>

请注意，如果颜色通过XAML作为StaticResource传递，则该行为是完美的。问题在于转换值

<Style x:Key="ButtonAnyColorStyle" TargetType="Button">
    <Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}" />
    <Setter Property="Template">
        <Setter.Value>
