In this React document (https://reactjs.org/docs/handling-events.html) it says, " ….. <button onClick={() => this.handleClick()}> Click me </button> …..

However, if this callback is passed as a prop to lower components, those components might ..

A page presents a dialog with an OK button. Under certain circumstances clicking the OK button fires its click-handler twice (event.timeStamp is identical).

I need to somehow separate when swiperjs was stopped by interaction or by mouse event. I have disableOnInteraction on true. Expected behavior: Autoplay swiper Pause autoplay on mouse enter Continue autoplay on mouse leave, and it’s NOT stopped by interaction before Stop autoplay on some interaction -> After stopping autoplay, mouse events shouldn’t work anymore ..
