Worked on stabilizing and improving the Outline Navigation feature in the marimo-team/marimo repository, focusing on resolving an issue with Table of Contents highlighting when multiple headings shared the same name. Addressed this by implementing a solution that tracks id-header pairs, ensuring only the correct heading instance is highlighted and improving navigation accuracy for users. The fix was delivered using React and TypeScript, maintaining the existing public API and minimizing changes to the outline/navigation logic. This targeted bug fix enhanced document accessibility and user experience, with ongoing attention to regression prevention and performance within the navigation module. No new features were added.
