When i ask for a session local file to be opened in the Canvas it usually doesn't work. I have to ask a few times until the AI realizes that the request resolves to a duplicated `files\files` path.

从 /chat 流程开始，在使用应用版本 1.1.12 的 Windows 10.0.26200 上，在 Canvas 中复现打开会话本地文件的请求。跟踪解析后的路径在哪里形成；完成标准是文件能够打开，且不会生成重复的 files\files 路径。
