避免在鼠标移开时重置动画

Question

我有一些图像，其中一个类由Intersection Observer动态添加到它们，以在用户滚动到它们时触发翻译动画。我只是将该类添加到此代码段中的图像中。

在每张图像上，我还有一个:hover动画，使它们具有“嗡嗡”效果。

但是，当用户将鼠标移出父级div时，将重播第一个动画。看来我在两个动画之间都有冲突。

如何避免这种情况？

.floating {
  width: 150px;
  height: 220px;
}

.show-bottom {
  animation: movefromtop 1s alternate;
}

@keyframes movefromtop {
  from { transform: translateY(-5em); }
  to { transform: translateY(0em); }
}

.icons-info > *:hover .floating { 
  animation: buzz 0.15s linear infinite;
}

@keyframes buzz {
  from { transform: translateX(3px) rotate(2deg); }
  to { transform: translateX(-3px) rotate(-2deg); }
}
