I'm exploring a potential fix for this issue where the enhance prompt feature incorrectly overwrites both the edit box and new message box. I'll investigate the message editing logic and open a PR to share progress.

I've opened PR #8554 with a fix for this issue: #8554

The fix adds a context parameter to distinguish between different ChatTextArea instances (main vs edit mode), ensuring that enhance prompt responses only affect the textarea that initiated the request.

All tests are passing and CI checks have completed successfully. Feedback welcome!
