Firefox中无法滑动

li标签的transform、transition属性没有设置成功，调用islider.slideNext();然后查看islider.slideIndex值变了，但是也没有切换，请问是什么问题？

Reproduce the issue in Firefox and inspect the li transform and transition behavior while calling islider.slideNext(). Compare the reported slideIndex value with the visible slide state. Done means identifying why Firefox does not apply the transition and confirming that the slide changes correctly without regressing the reported index.
