嵌套组件中同时出现wx:for和repeat会导致repeat中循环变量失效

comp.wpy

<template>
  <view class="comp">
    <slot></slot>
  </view>
</template>

<script>
  import wepy from 'wepy'

  export default class Comp extends wepy.component {}
</script>

index.wpy

<template>
  <view>
    <wrapper></wrapper>
  </view>
</template>

<script>
  import wepy from 'wepy'
  import wrapper from './wrapper'

  export default class Index extends wepy.page {
    components = {
      wrapper
    }
  }
</script>

wrapper.wpy

<template>
  <view id="wrapper">
    <view id="for1">
      <view wx:for="{{ arr1 }}">{{ item }}</view>
    </view>
    <view id="for2">
      <repeat for="{{ arr2 }}">
        <comp>{{ item }}</comp>
      </repeat>
    </view>
  </view>
</template>

<script>
  import wepy from 'wepy'
  import comp from './comp'

  export default class Wrapper extends wepy.component {
    components = {
      comp
    }

    data = {
      arr1: ['a', 'b', 'c'],
      arr2: ['1', '2', '3']
    }
  }
</script>

wrapper_fixed.wpy

<template>
  <view id="wrapper">
    <view id="for1">
      <view wx:for="{{ arr1 }}" wx:for-item="for1Item" wx:for-index="for1Index">{{ for1Item }}</view>
    </view>
    <view id="for2">
      <repeat for="{{ arr2 }}">
        <comp>{{ item }}</comp>
      </repeat>
    </view>
  </view>
</template>

<script>
