Bug description

When loop is set to true, I can see the [data-swiper-slide-index] attached to all the swiper slides. But it isn't available otherwise. I have a use case where I have image with unique ID inside each of the slide. When I match the id of that image, I should be able to get the index of the parent slide & use slideTo(index) to go to that slide.
