[General] Focus keep changing while agent working, blocking me to write anything in the chat.

**Mood:** :(
**Category:** General

While the agent working and editing a .md file, the focus from the chat changes to the markdown editor autoamtically and constantly, which prevents me writing follow up messages while waiting the agent wip.. this is annoying. even right now writing this message in this modal has the same bug

从 /chat 体验开始，在 macOS 上使用报告的应用版本 1.0.12 和 Notionish 主题，重现 agent 编辑 .md 文件时的焦点变化。跟踪 agent 工作期间哪些聊天视图和 Markdown 编辑器视图获得焦点。当可以在聊天中输入后续文本，且焦点不会移动到编辑器时，即表示完成。
