airtestIDE（1.2.13）poco辅助窗元素识别以及执行问题
**描述问题bug**
使用airtestIDE（1.2.13）poco辅助窗有的时候可以识别微信中小程序页面的元素，有的时候不能，测试的微信版本是（7.0.22和8.0.20），已经进行了webview的设置了，即使识别到了微信中的元素编写脚本之后，然后整体执行脚本也还是会报错，识别不到元素
(简洁清晰得概括一下遇到的问题是什么。或者是报错的traceback信息。)使用的pocoui 是 1.0.85，pocoservice-debug.apk是1.0.0.45的。

（在这里粘贴traceback或其他报错信息）

**预期效果**
(预期想要得到什么、见到什么)
就是可以在微信小程序页面中使用poco进行识别元素并且可以使用python3命令执行.air文件或是可以在airtestIDE中可以整体执行脚本
**相关截图**
(贴出遇到问题时的截图内容，如果有的话)

不能获取到小程序的元素
