Slider breaks when adding new images

In https://stackblitz.com/edit/react-slick-slider-issues-3cemya, calling **randomuser API** and passing the initial data to the slider. Keeping track of the **current slideindex** using **afterChange** and on each update calling **useEffect** to fetch new data from the **randomuser API** and then concatenate the new results to the old results. sometimes the slider breaks when adding new data and resets to normal after few seconds.
