滑动：已定义循环和自动播放，但不起作用

Question

我有一个使用swiper库的博客模块。

我在JS中定义了loop和autoplay，但是它会自动播放一次，然后在最后一张幻灯片上，它不会返回到第一张幻灯片。

此外，您可以向下滚动到下一张幻灯片，但不能向上滚动？

演示：

var swiper = new Swiper('.blog-slider', {

  spaceBetween: 30,
  effect: 'fade',
  disableOnInteraction: true,
  loop: true,

  autoplay: {
    delay: 10000,
  },

  mousewheel: {
    invert: false,
  },

  pagination: {
    el: '.blog-slider__pagination',
    clickable: true,
  }

});

.blog-slider {
  width: 95%;
  position: relative;
  max-width: 800px;
  margin: auto;
  background: #FFF;
  box-shadow: 0px 14px 80px rgba(34, 35, 58, 0.2);
  padding: 25px;
  border-radius: 25px;
  height: 400px;
  transition: all 0.3s;
}

@media screen and (max-height: 500px) and (min-width: 992px) {
  .blog-slider {
    height: 350px;
  }
}
.blog-slider__item {
  display: flex;
  align-items: center;
}

.blog-slider__item.swiper-slide-active .blog-slider__content > * {
  opacity: 1;
  transform: none;
}
.blog-slider__item.swiper-slide-active .blog-slider__content > *:nth-child(1) {
  transition-delay: 0.3s;
}
.blog-slider__item.swiper-slide-active .blog-slider__content > *:nth-child(2) {
  transition-delay: 0.4s;
}


.blog-slider__content {
  padding-right: 25px;
}

.blog-slider__content > * {
  opacity: 0;
  transform: translateY(25px);
  transition: all 0.4s;
}
.blog-slider__code {

  }
}
.blog-slider .swiper-container-horizontal > .swiper-pagination-bullets, .blog-slider .swiper-pagination-custom, .blog-slider .swiper-pagination-fraction {
