用硒显色剂无法获得window_handles

Question

最近，在将chrome更新为55+之后，我尝试通过句柄获取窗口句柄时，开始收到错误：

未知错误: DevTools返回未知type:shared_worker

以下是一个原始的回应：

      "sessionId": "eb9c00d1-69b5-442f-a7ec-22ec3f66ebe8",

      "value": {

...
}

对于单个和多个制表符，它都会失败。而且，/session/:sessionId/window_handle似乎工作得很好。

显色剂: 2.26.436421

硒: 2.53.1

铬: 55.0.2883.95

有谁知道怎么解决这个问题吗？

这是ChromeDriver中的一个bug，它在第2.27版中得到了修正：
