default-checked-keys可以设置默认选中的节点，就算是懒加载的子节点也是可以的。 |

只有展开了才有选中状态 |

这种的得手动设置父节点的状态，因为在懒加载状态下父节点无法知道子节点的选中了哪些，所已无法自动设置父节点状态。 |

问题：
issue(#21932)
bug产生原因：
由于懒加载后doCreateChildren函数使用foreach的方式新增child，每次新增一个child都会执行reInitChecked函数对父节点的选中状态重置。所已第一个child选中后，第二个节点在选中时reInitChecked认为所有子节点（本来有n>2个子节点，只是foreach刚创建2个而已）都选中了，然后导致后面所有新增的child都会因为父节点已选中而被设置为选中。
解决方法：
将节点的loading状态放到doCreateChildren函数完成之后并在reInitChecked计算父节点选中状态时对loading中的节点不处理。等loading完成后由回调函数重新计算父节点的选中状态。
