我进行了语义缩放并将其放入弹出窗口中。它在放大和缩小方面工作正常，但是当它从缩小的选定项目放大时，它不会将放大的列表放在正确的位置，但它总是显示放大列表视图中的第一个项目. 当我在页面上放置相同的代码时，它可以正常工作。这是弹出和页面的代码

为了看到正确的行为，必须使用 ScrollViewer 将 SemanticZoom 包装在 Flyout 中。代码如下

                <Flyout Placement="Bottom">
                <StackPanel Orientation="Horizontal" Width="500">

                    <ScrollViewer>
                            <SemanticZoom Width="300"  >
                                <SemanticZoom.ZoomedInView>
                                   ...
                                   ...
                                 </SemanticZoom.ZoomedOutView>
                             </SemanticZoom>
                    </ScrollViewer>
