I'm exploring a potential fix for the issue where messages disappear at choice prompts. I'll investigate the chat history and message handling logic to ensure user messages are properly preserved when making selections.

I've successfully implemented a fix for this issue! 🎉

Pull Request: #7317

Summary of the fix:

The issue was that messages typed at follow-up question prompts were being cleared from the input field without being preserved in any accessible history. This meant that if the backend processing failed or the user navigated away, the message was lost.

Solution implemented:

1. Added local message history buffer: Created a local state in the usePromptHistory hook that stores messages immediately when the user presses Enter, before they are cleared from the input field.

2. Integrated with ChatTextArea: Modified the handleKeyDown function to call addToLocalHistory before sending the message, ensuring the message is preserved locally.

3. Smart deduplication: Added logic to prevent duplicate entries when messages are eventually confirmed by the backend.

4. Seamless history navigation: The locally saved messages are combined with backend-confirmed messages, so users can navigate through their complete history using the up-arrow key.

Testing:

• All existing tests pass ✅
• The fix preserves messages at choice prompts as expected
• Up-arrow navigation works correctly with locally saved messages

The PR is currently going through CI checks. Once they pass, the fix will be ready for review and merge.
