HarmonyOS web加载url没有展示全

使用如下demo

// main/ets/pages/index.ets
import { webview } from '@kit.ArkWeb';

@Entry
@Component
struct Index {
  webviewController: webview.WebviewController = new webview.WebviewController();

  build() {
    Row() {
      Column() {
        Web({ src: "https://xxx", controller: this.webviewController })
          .domStorageAccess(true)
          .mixedMode(MixedMode.All)
          .width("100%")
          .height("100%")
      }
      .width('100%')
    }
    .height('100%')
  }
}
