为什么按钮的边框厚度不改？

Why the border thickness of the Button doesn't change?

如果我更改边框厚度为1或100，它没有问题。一样的。我想使用的风格，而不是改变它自定义模板

If I change the border thickness to 1 or 100, it doesn't matters. It's the same. I would like to change it using Style, not Custom Template.

 <Window x:Class="GUI.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <Style x:Key="newYellowButton" TargetType="{x:Type Button}">
        <Setter Property="Width" Value="100"/>
        <Setter Property="Height" Value="100"/>
        <Setter Property="Background">
            <Setter.Value>
                <RadialGradientBrush Center="0.5,0.5" GradientOrigin="0.5,0.5" RadiusX="0.5" RadiusY="0.5" SpreadMethod="Pad" ColorInterpolationMode="SRgbLinearInterpolation">
                    <GradientStop Color="#FFEEEE3B" Offset="0.5" />
                    <GradientStop Color="#FFF0E49A" Offset="1" />
                </RadialGradientBrush>
            </Setter.Value>
        </Setter>
        <Setter Property="BorderThickness" Value="9"/>
        <Setter Property="BorderBrush" Value="Blue" />
        <Setter Property="Padding" Value="-4"/>
    </Style>
</Window.Resources>
<Grid>
    <Button Style="{StaticResource newYellowButton}" Content="Ok"/>
</Grid>
