Keep Last Opened Thread "Opened" while in Canvas.

Don’t really know if it is a bug or a feature to request:
1. Open a chat thread,
2. Open Canvas
3. Return to Chats
4. You are returned to a new chat.

I’ve been using a thread to improve image prompts, but having to select the thread, which is the last opened, is somewhat inefficient.

It would feel natural for the chat that was open, remain “open”.
1. Open a chat thread,
2. Open Canvas
3. Return to Chats
4. You are returned to the chat thread that was opened before entering Canvas
