Worked on the nuxt/ui repository to enhance the stability of touch interactions across overlay components. Addressed a persistent issue where modals, drawers, popovers, and slideover elements would close unexpectedly during pointer-down events, particularly on touch devices and in scrollable contexts. Developed a cross-component utility in TypeScript and Vue that accurately detects pointer-down events outside overlays, preventing false positives when target nodes are removed or when users interact with scrollbars. Focused on UI/UX design principles to ensure overlays behave reliably, resulting in a more consistent user experience. The work involved fixing a complex bug rather than introducing new features.
