刚进入小程序的时候，底部tabBar是正常的

但是反复点击切换不同的tab页面（大概切换三次）就会突然出现tabBar字体变大的情况

这个问题在安卓和iOS系统中没有出现，目前仅出现在鸿蒙6系统当中，这是为什么呢？有人遇到这个情况吗？

以下是提供的代码片段

<cover-view class="custom-tab-bar">
  <cover-view wx:for="{{list}}" wx:key="index" class="tab-bar-item" data-path="{{item.pagePath}}" data-index="{{index}}" bind:tap="switchTab">
    <cover-image class="icon" src="{{selected === index ? item.selectedIconPath : item.iconPath}}"></cover-image>
    <cover-view class="{{selected === index ? 'name checked' : 'name'}}">{{item.text}}</cover-view>
  </cover-view>
</cover-view>

.custom-tab-bar {
  position: fixed;
  left: 0;
  bottom: 0;
  z-index: 999;
  padding-bottom: constant(safe-area-inset-bottom);
  padding-bottom: env(safe-area-inset-bottom);
  width: 100%;
  height: 71px;
  background-color: #fff;
  border-top: 0.5px solid #E3E3E3;
  display: flex;
}
.custom-tab-bar .tab-bar-item {
  height: 71px;
  flex: 1;
  display: flex;
  flex-direction: column;
  align-items: center;
}
.custom-tab-bar .tab-bar-item .icon {
  margin: 10px auto 2px;
  width: 28px;
  height: 28px;
}
.custom-tab-bar .tab-bar-item .name {
  color: rgba(0, 0, 0, .3);
  font-size: 12px;
  line-height: 15px;
}
.custom-tab-bar .tab-bar-item .name.checked {
  color: #1368fb;
}
