Mar 1, 2026March 2026 – Lucca-front: Delivered significant tooltip performance and accessibility improvements to enhance UI responsiveness and accessibility at scale. Replaced heavy per-cycle layout reads with a lazy, signal-driven observer architecture for ellipsis detection in LuTooltipTriggerDirective, dramatically reducing memory leaks and layout thrashing. Implemented a layered, event-driven observer chain with IntersectionObserver, ResizeObserver, and MutationObserver, activated only when needed. Strengthened accessibility by ensuring aria-describedby targets are reliably present in the DOM and pre-creating the overlay container for screen readers. Reused and fully disposed overlay lifecycle to eliminate DOM leaks across hover cycles. Added robust performance and stress tests, including a 500-tooltip grid scenario, to validate mount/unmount and hover performance under realistic workloads.
