Drag and drop is broken with firefox + wayland in arch linux, so I can't upload the file at the moment. Here's a link to the video uploaded to the TanStack Discord server

Additional context

No response

从 https://tanstack.com/router/latest 开始，通过运行一次 AI 搜索，然后在生成期间和生成之后分别关闭对话框来重现卡死。跟踪文档站点搜索对话框在 frontend 中的关闭路径，并验证在任一流程之后站点的正常功能仍能响应。
