研究方向
Review the Carousel component source code in ant design, particularly the dot click handler and lazyLoad='ondemand' logic. The bug is that clicking the 2nd dot displays the 1st element, suggesting a index mismatch when lazy loading is on demand. Check the ondemand lazy load implementation to see if it affects the active index calculation or if the component fails to render the correct slide after dot click. Look at files like components/carousel/index.tsx and related hooks.
