1. 在第一个页面显示一张图
2. 跳转到另一个有很多图的页面，其中一张和第一个页面那张图地址相同
3. 快速点击返回
4. 第一个页面的图片消失

和返回的时机有一定关系，大致上是第二个页面的图开始加载，但还没有全加载出来的时候点返回，多试几次总能复现。在开发工具和安卓客户端都能重现，第二个页面图越多越容易重现。

安卓客户端重现视频：

第一个页面 /pages/index/index 代码：

<navigator url="/image/index">
  <image src="{{url}}"></image>
  <view>上面是图</view>
</navigator>

Page({
  data: {
    url: '',
    list: [],
  },

  onLoad() {
    setTimeout(() => {
      this.setData({
        url: 'https://mszm.dtzhuanjia.com/image/team/mijuejubensha/logo.jpg',
      });
    }, 1000);
  },
})

第二个页面 /pages/image/index 代码：

<image src="{{url}}"></image>
<image wx:for="{{list}}" src="{{item}}"></image>

Page({
  data: {
    url: '',
    list: [],
  },

  onLoad: function () {
    setTimeout(() => {
      this.setData({
        url: 'https://mszm.dtzhuanjia.com/image/team/mijuejubensha/logo.jpg',
        list: [
