小程序中使用scroll-view组件，内容高度未超过容器高度时依然可以上下滑动小段距离的问题

<view class="home-page"> <scroll-view class="scroll-box" scroll-y="{{true}}" style="height: {{scrollBoxHeight}};" scroll-with-animation="{{true}}" upper-threshold="{{50}}" lower-threshold="{{50}}" bindscrolltoupper="handleScrollToupper" bindscrolltolower="handleScrolltolower" bindscroll="scroll"> <!-- <view class="test-box" >测试测试测试</view> --> <view class="nav-bar-box {{navBarSticky === true ? 'nav-bar-sticky': ''}}"> <nav-bar bind:switchChannel="switchChannel" activeChannel="{{}}"></nav-bar> </view> <view tt:if="{{navBarSticky}}" style="height: {{navBarDistance}}"></view> <view class="template-list-item"> <template-list tt:if="{{ > 0}}" dataList="{{dataList}}" activeChannel="{{}}"></template-list> </view> <view class="no-data" tt:if="{{hasAllData}}"> <text>没有更多了</text> </view> </scroll-view> </view>
