使用官方示例web_demo.py时，gradio页面报错，无法显示模型应答结果

[xinaiwunai]

通过命令启动成功，如下所示：

也成功弹出浏览器并进入示例页面，任意输入一句话，提交后。能监控到请求得到了正确的响应，如下图：

但是页面却出现js错误，显示不出应答结果。
具体情况是：大模型响应的第一个字“你”会正常出现，然后试图显示下一个字“好”时就直接报错，同时第一个字“你”也一起消失了。且后续也无法提交新的输入。
浏览器监控console提示如下js错误：

dom.js:238  Uncaught (in promise) DOMException: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node.

你先降级到3.39.0试试

[xinaiwunai]

gradio降级3.39.0后，网页正常了。这么说，就是gradio 3.50.2有问题了。
