编译后的代码出现逻辑错误导致运行结果未达预期

[ctcx]

问题描述
发现这个问题是在使用 taro-ui 组件 AtIndexes 时显示错误

复现步骤

使用 AtIndexes 组件，每组数据达到20个以上时会出现（非报错）

以下是我查看AtIndexes组件编译后的代码片段

var loopArray19 = list.map(function (dataList, _anonIdx3) {
        dataList = {
          $original: (0, _index.internal_get_original)(dataList)
        };
        var $anonymousCallee__0 = dataList.$original.items ? dataList.$original.items.map(function (item, _anonIdx) {
          item = {
            $original: (0, _index.internal_get_original)(item)
          };
          var $compid__152 = (0, _index.genCompid)(__prefix + "zmjkaPGoJN" + _anonIdx3 + _anonIdx);
          _index.propsManager.set({
            "title": item.$original.name,
            "onClick": _this4.handleClick.bind(_this4, item.$original)
          }, $compid__152);
          return {
            $compid__152: $compid__152,
            $original: item.$original
          };
        }) : [];
        return {
          $anonymousCallee__0: $anonymousCallee__0,
          $original: dataList.$original
        };
      });

// ```js
主要是 这一行：
var $compid__152 = (0, _index.genCompid)(__prefix + "zmjkaPGoJN" + _anonIdx3 + _anonIdx);
// ```
当变量：
_anonIdx3 为 1  _anonIdx 为 10 
_anonIdx3 为 11  _anonIdx 为 0 
会出现变量 $compid__152 值相同的情况

我不知道这行代码是哪里生成的，所以不知道在哪里修改；但是如果在 变量 _anonIdx3 + _anonIdx 之间再加个 '_' 如：_anonIdx3 +'_'+ _anonIdx，就可以避免这个问题了。

找一下你的源代码贴出来，有一个循环返回 JSX 组件，用 list 来循环，循环回调的第一个变量是dataList

我用的是taro-ui 的组件，组件代码是：
<AtIndexes list={brandList} />
brandList数据是（使用以下数据能正常显示，但是字母B组内缺少了包括本田在内的几个品牌，同时多出了 纳智捷 等其他非字母B组的数据）：
