Month 2025-11 – Big-Design: Dropdown reliability and accessibility improvements within modal contexts. Implemented targeted bug fixes, expanded test coverage, and strengthened dropdown stability across modal boundaries to improve user experience and accessibility in complex UI scenarios. Key deliverables: - Dropdown interaction reliability inside modals: ensured dropdown item clicks register reliably, updated focus trap to allow interactions with dropdowns/listboxes outside the modal when appropriate, and added tests for modal contexts. - Disabled dropdown items do not trigger onItemClick: prevented onItemClick for disabled items, updated dropdown logic, and added tests for both keyboard and mouse interactions.
