Prompt history is shared across threads

What issue are you seeing?

When I hit the up arrow in a certain thread to see what I asked last, it shows me the last prompt I did, no matter the thread, which often times means it happened in another thread. It would be good to just limit the prompt history to the history in this current thread, or at least have this be a setting to choose between local or global history.

What steps can reproduce the bug?

Launch multiple threads with different prompts and scroll through history with up arrow.

What is the expected behavior?
