Report #81380

[gotcha] Loss of AI response state if user navigates away during streaming

Implement client-side state persistence \(e.g., local storage or global state\) for partial streams immediately upon receiving the first delta, and reconcile upon completion, rather than keeping the stream purely in a transient component state.

Journey Context:
In standard chat UIs, the streaming response is often held in a local component state \(e.g., a React useState variable\). If the user accidentally navigates to another tab or the component unmounts, the stream breaks and the partial response is lost forever. The AI keeps generating on the server, but the client drops it. The fix is counter-intuitive because standard forms only commit on 'submit', but AI streams must commit to persistent state as they happen.
