uniapp解决scroll滑动之后被u-sticky挡住的问题

问题：页面触底加载之后，回到头部，顶部数据被遮挡

将上的swiper-list样式高度调整成90vh

<view class="main">
	<u-sticky bgColor="#fff">
		<u-tabs ref="uTabs" :list="tabList" lineWidth="26" lineHeight="11" :lineColor="`url(${lineBg}) 100% 100%`"
		:activeStyle="{
	        color: '#303133',
	        fontWeight: 'bold',
	        transform: 'scale(1.05)'
	     }"
	     :inactiveStyle="{
	        color: '#606266',
	        transform: 'scale(1)'
		  }" 
		  itemStyle="padding-left: 15px; padding-right: 15px; height: 34px;margin-bottom: 6px"  @change="tabsChange" @click="tabsChange" :current='swiperCurrent'>
	  </u-tabs>
	</u-sticky>
	<swiper :current="swiperCurrent" @animationfinish="animationfinish" class="swiper-list">
		<swiper-item class="swiper-item" v-for="(item, index) in tabs" :key="index">
			<scroll-view scroll-y style="width: 100%;height: 100%;" @scrolltolower="onreachBottom" refresher-enabled='true'
				<list-box></list-box>
			</scroll-view>
		</swiper-item>
	</swiper>
