下面的 xaml 代码与 Expander 的边界重叠。当我运行它并单击第一个扩展器选项时，它将展开并显示富文本框。但我无法滚动它。但是第二个扩展器没有问题。如何解决这个问题呢？

    <Expander Header="Certificate" Margin="201,85,101,143">
        <ScrollViewer Width="283" Height="106">
            <RichTextBox Name="richTextBox1" Margin="0,0,0,0" Height="82" Width="221">
            <FlowDocument>
                <Paragraph>
