All browsers in my PC have same problem. when i use Swiper JS freeMode? [closed]

Swiper js freeMode goes wild when I swipe either direction. It happens in Google Chrome and in Edge too. but when I tried in “CodeSandBox” it works fine. but on Jsbin.com it works not that good(sometimes slides lag and when you touch second time it jumps straight to last or first slide).

CodeSandbox

<div class="swiper mySwiper">
      <div class="swiper-wrapper">
        <div class="swiper-slide">Slide 1</div>
        <div class="swiper-slide">Slide 2</div>
        <div class="swiper-slide">Slide 3</div>
        <div class="swiper-slide">Slide 4</div>
        <div class="swiper-slide">Slide 5</div>
        <div class="swiper-slide">Slide 6</div>
        <div class="swiper-slide">Slide 7</div>
        <div class="swiper-slide">Slide 8</div>
        <div class="swiper-slide">Slide 9</div>
      </div>
      <div class="swiper-pagination"></div>
</div>

<script src="https://unpkg.com/swiper/swiper-bundle.min.js"></script>

    
    <script>
      var swiper = new Swiper(".mySwiper", {
        
   `your text`     slidesPerView: 3,
        spaceBetween: 30,
        freeMode: true,
        pagination: {
          el: ".swiper-pagination",
          clickable: true,
        },
      });
</script>

I tried searching in Google but nothing found.
