Summary0050727: Memory leak in Carousel.jsx - DOM event listeners are not being removed
DescriptionThe Carousel.jsx component has a memory leak because it is registering DOM events on a useEffect hook but is never unregistering them.

The useEffect hook should return a function that will be invoked when unmounting the component and that will unregister the DOM events
Steps To ReproduceSee the code here [1], it is adding two event listeners but never removing them. It should removee them like it is done here [2]
