HarmonyOS 设置了网页超时加载，webview没有走onErrorReceive回调

示例参考：

@Entry({ routeName: entryName })
@Component
export struct JDRHSamplePage {

  build() {
    Stack({ alignContent: Alignment.TopStart }) {
      Column() {
        Column() {
          Web({
            src: '',
            controller: this.controller
          }).onControllerAttached(()=>{
            try {
              //超时设置
              web_webview.WebviewController.setConnectionTimeout(30);
            } catch (e) {
              JDRHLogger.error("setConnectionTimeout"+e);
            }
            this.checkSampleVerifyInFewSeconds();
            this.controller.loadUrl(this.sample_page_Url,[{ headerKey: "x-rp-content", headerValue: this.x_rp_content }])
          }).javaScriptAccess(true)
            .domStorageAccess(true)
            .onPageEnd((event) => {
              JDRHLogger.info("抽样页面加载完成");
              this.isShowLoading = false;
            })
            .onErrorReceive((event) => {
              JDRHLogger.info("抽样页面加载错误");

            })

目前onErrorReceive回调，支持连接超时回调， 不支持服务端响应超时
