HarmonyOS鸿蒙Next中webview加载的页面获取定位失败

这个网址我们试了下web加载出来的位置不准确，但是我们再华为浏览器中打开显示的位置是准确的

请参考如下代码

import { webview } from '@kit.ArkWeb';
import abilityAccessCtrl from '@ohos.abilityAccessCtrl';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  @State url: string = 'https://ywtb.ga.tj.gov.cn/frontend/weixin/';

  controller: webview.WebviewController = new webview.WebviewController();

  onBackPress() {
    if (this.controller.accessStep(-1)) {
      this.controller.backward();
      return true
    } else {
      return false
    }
  }

  aboutToAppear() {
    webview.WebviewController.setWebDebuggingAccess(true);
    let atManager = abilityAccessCtrl.createAtManager();
    atManager.requestPermissionsFromUser(getContext(this), ['ohos.permission.CAMERA',"ohos.permission.MICROPHONE","ohos.permission.LOCATION","ohos.permission.APPROXIMATELY_LOCATION"])
      .then(data => {
        let result: Array<number> = data.authResults;
        let hasPermissions1 = true;
        result.forEach(item => {
          if (item === -1) {
            hasPermissions1 = false;
          }
        })
        if (hasPermissions1) {
          console.info("hasPermissions1");
        } else {
          console.info(" not hasPermissions1");
        }
      }).catch(() => {
      return;
    });
  }
