HarmonyOS web加载链接显示效果异常

要设置下ua。参考以下demo:

import WebView from '@ohos.web.webview';

@Entry
@Component
struct Index {
  private webController: WebView.WebviewController = new WebView.WebviewController();

  async aboutToAppear(): Promise<void> {
    // 配置web开启调试模式
    WebView.WebviewController.setWebDebuggingAccess(true);
  }

  build() {
    RelativeContainer() {
      Web({ src: "https:www.huawei.com", controller: this.webController })
        .onControllerAttached(() => {
          this.webController.setCustomUserAgent('Mozilla/5.0 (xxx; VRD-AL10; HMSCore 6.3.0.331) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.88 HuaweiBrowser/12.0.4.1 Mobile Safari/537.36')
        })
        .domStorageAccess(true)
        .javaScriptAccess(true)
        .imageAccess(true)
        .onlineImageAccess(true)
        .fileAccess(true)
        .mixedMode(MixedMode.All)
    }
    .height('100%')
    .width('100%')
  }
}
