What happened

1. 构建工作流并提问后，当前对话窗口只回复json结构的回答，每次问答和回复都会生成一个新的对话窗口；
   新的对话窗口可以正常展示图表、代码，但提问会报错，只能在原有的窗口提问。
2. （工作流和chat data都有）绘制多种图表时，查看其他类型图表，滑动鼠标就会返回默认推荐的图表，无法正常查看其他绘制图表。

What you expected to happen

工作流对话在同一窗口完成问答，且答案格式正常显示；
可正常切换图表类型

How to reproduce

1. 源码部署v0.7.0或v0.7.2（uv安装OpenAI Proxy相关依赖），或docker部署最新版镜像
2. vllm运行本地llm，embeddings模型也本地运行，以api的格式调用
3. 构建工作流
4. 问答
