Steps to reproduce the problem:
Scenario 1:

1. Chat with assistant and ask for a response that is going to be large.
2. When message response is being streamed , stop(interrupt) the message.
3. Quit this thread and revisit it back.

Notice that the chat message and the partial response from step 2 are lost in the thread view

Scenario 2:

1. Chat with assistant and ask for a response that is going to be large.
2. When message response is still being streamed , quit the thread (by revisiting another thread)
3. Revisit the thread from step1.

Notice that the chat message and the partial response from step 2 are lost in the thread view
