自定义TabBar在基础库v2.6.2+的生命周期attached重复执行 - WXOPEN Club

customBar代码在基础库__2.6.1__和__2.5.0__版本下运行，进入页面时先执行的customBar的生命周期函数attached，并打印了TarBar前缀的日志，然后在页面onShow函数中打印了进入某某页面日志，此时两个函数获取的当前页的WebViewId和TabBar的ExparserNodeId相同

然而把基础库改为__2.6.2+以后，BUG来了，注意时间戳，进入页面时执行customBar的attached函数和页面的onShow函数后，再次执行了customBar的attached函数，结果就是当前页的customBar显示的是上一次渲染的数据__

代码用的是你们官网提供的自定义tabbar示例代码：https://developers.weixin.qq.com/s/jiSARvmF7i55
