when slidesPerView is auto，use virtual errors

[qiang-niu]

swiperOptionThumbs: {
slidesPerView: 'auto',
preloadImages: false,
observer: true,
observeParents: true,
watchSlidesVisibility: true,
resizeObserver: true,
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
virtual: {
slides: [],
renderExternal(data) {
vm.virtualList = data
console.log(vm.virtualList)
},
},
},
virtualList: {
slides: [],
offset: 0,
},
