Scroll嵌套web，如何实现可以流畅的滑动，Web内容高度会变化

import web_webview from '@ohos.web.webview';  
@Entry  
@Component  
struct NestedScroll {  
  private scrollerForScroll: Scroller = new Scroller()  
  controller: web_webview.WebviewController = new web_webview.WebviewController();  
  
  build() {  
    Flex() {  
      Scroll(this.scrollerForScroll) {  
        Column() {  
          Text("原生区域")  
            .width("100%")  
            .height("40%")  
            .backgroundColor(0X330000FF)  
            .fontSize(16)  
            .textAlign(TextAlign.Center)  
  
          Web({ src: 'www.harmonyos.com', controller: this.controller })  
            .height("200%")  
            .nestedScroll({scrollForward: NestedScrollMode.SELF_FIRST, scrollBackward: NestedScrollMode.PARENT_FIRST})  
        }  
      }  
      .width("100%").height("100%")  
    }.width('100%').height('100%').backgroundColor(0xDCDCDC).padding(20)  
  }  
}
