How to fix the problem with 3D animation CSS on iOS (Safari / Chrome)

Question

I have something like browser game. On click user throw dices. Dices fall through shadow, but there are different block and dice has z-index : 3 and shadow z-index : 2; This problem only on iOS. For animation use library anime.js. Maybe someone had the same problem.

Try to add screenshot for show the problem:

.dice {
  width: 144px;
  height: 144px;
  left: -200px;
  top: -450px;
  z-index: 3;
  transform-style: preserve-3d;
  backface-visibility: hidden;
  transform: translateZ(-72px) rotateX(313deg) rotateY(226deg) scale3d(0.35, 0.35, 0.35);
  z-index: 3;
  .cube_face {
    width: 144px;
    height: 143px;
    border: 1px solid #f5f3e6;
    border-radius: 15px;
  }
}

<div class="diceShadow"></div>
<div class="dice">
  <div class="cube_face cube_face_front"></div>
  <div class="cube_face cube_face_back big-shadow"></div>
  <div class="cube_face cube_face_right"></div>
  <div class="cube_face cube_face_left shadow"></div>
  <div class="cube_face cube_face_top"></div>
  <div class="cube_face cube_face_bottom"></div>
</div>

anime({
  targets: dices[count],

Problem solved! I had DOM elements that were outside parent`s block. When I positioned them to parent block area and add opacity, to hide them - my dices fell into place. Example: were :

#train {
                width: 158px;
                height: 146px;
                transition: all 0.4s ease-in;
                background: url('../img/train.png') no-repeat center;
                background-size: cover;

                &[data-show='false'] {
                    left: -100%;
                    top: -100%;
                }

                &[data-show='true'] {
                    left: 9%;
                    top: 14%;
                }
            }

now:

#train {
                width: 158px;
                height: 146px;
                transition: all 0.4s ease-in;
                background: url('../img/train.png') no-repeat center;
                background-size: cover;

                &[data-show='false'] {
                    left: 0%;
                    top: 17px;
                    opacity: 0;
                }

                &[data-show='true'] {
                    left: 9%;
                    top: 14%;
                    opacity: 1;
                }
            }
