The default selection data of the tree under checkstrict is a one-dimensional array, but once clicked, it becomes a two-dimensional array of checked: and halfchecked

• I have searched the issues of this repository and believe that this is not a duplicate.

Version

3.1.0-rc.2

Environment

chrome

Reproduction link

[https://www.undefinded.com](https://codesandbox.io/s/f0w5es?file=/src/App.vue)

Steps to reproduce

checkStrictly 下的tree 默认选择数据是 一维数组[1,2,3], 但是一点击 就变成 checked:[1,2,3] 和 halfChecked:[] 的二维数组,
我一开始传 二维数组, 整个tree 都点不了了

What is expected?

传入的数据是一维, 点击后的动态数据 一维, 或者 传入的二维 点击也是二维
The incoming data is one-dimensional, the dynamic data after clicking is one-dimensional, or the incoming two-dimensional click is also two-dimensional

What is actually happening?

Hello @yemaozi999. Please provide a online reproduction by forking this link for vue2、 link for vue3 or a minimal GitHub repository. Make sure to choose the correct version.

你好 @yemaozi999, 我们需要你提供一个在线的重现实例以便于我们帮你排查问题。你可以通过点击 此处 for vue2、 此处 for vue3 创建一个 codesandbox 或者提供一个最小化的 GitHub 仓库。请确保选择准确的版本。

不是二维数组。是类似这种：
const checkedKeys = ref({ checked: ['0-0-0', '0-0-1'], halfChecked: [] });

这样数据格式变化, 会出现处理的问题, 要写两种方法来区分 初始数据 和点击数据
const menuIds = ref<number[]>([])

const checkshow = (id:number)=>{
if(typeof menuIds.value['checked']!='undefined'){ //判断点击后的数据
if(menuIds.value['checked'].includes(id)){
return true;
}
}else{
if(menuIds.value.includes(id)){ //判断点击前的数据
return true;
}
}
return false;
}

而且在checkStrictly 模式下, 无论怎么点 halfChecked 数组都不会有值

checkStrictly 下传单数组没来就是错误的，只是组件做了容错处理。
checkStrictly 下 halfChecked 要手动控制，因为你不可能点击出半选啊

checkStrictly为false的情况下，onCheck回调没有返回halfChecked的值，只是返回checked值的数组，但组件当前的状态是父子节点选中状态存在关联。
当checkStrictly为true时，onCheck会返回带halfChecked的对象，但此时父子节点没有关联，所以halfChecked永远是空数组。
所以是不是onCheck回调的形参在checkStrictly不同情况下传反了？
