HarmonyOS Web组件高度设置问题，Web组件内容被遮挡

@Entry 
@Component 
struct Index { 
  @State message: string = 'Hello World'; 
  webController: webview.WebviewController = new webview.WebviewController(); 
  build() { 
    Column() { 
      Text(this.message) 
        .fontSize(50) 
        .fontWeight(FontWeight.Bold) 
 
      Column() { 
        Row() 
          .backgroundColor(Color.Yellow) 
          .width('100%') 
          .height(100) 
 
        Web({ src: $rawfile('index.html'), controller: this.webController }) 
          .flexGrow(1) 
          .flexShrink(0) 
          .width('100%') 
      } 
      .backgroundColor(Color.Green) 
      .width('100%') 
      .height(600) 
 
    } 
    .height('100%') 
    .width('100%') 
 
  } 
}
