During March 2026, Haibo Wang focused on stabilizing the chat interface for the bytedance/deer-flow repository, addressing a persistent UI bug where long chat messages would overflow and disrupt the layout. Using React and TypeScript, Haibo implemented precise CSS and DOM adjustments to ensure that lengthy messages are now clipped, maintaining visual consistency across devices and reducing rendering anomalies. This targeted fix improved the reliability and maintainability of the chat UI without introducing new features. The work demonstrated careful attention to UI/UX principles, with clear, traceable commits that support future maintenance and reinforce the overall quality of the frontend codebase.
