fix(core): fix getClosestPosition error when component nesting

[bcguan2008]

问题

当组件嵌套了多个组件时，会发生 closestPosition 计算不对的问题

拿Card 举例，在 behavior 里设置了 Card 不能 append 到 Card

录制了一个 gif 图，拖拽滑动到子组件时光标位置计算不对。 拖拽到 input， textArea 和 password 分别发生了多次光标跳动，无法给予拖拽用户一个准确的预期

原因

getClosestPosition 方法做了 closestNode 的重计算（主要是 onMove 事件在方法外会修改 closestNode，所以重计算 closestNode 没有问题 ），但没有进行 isAfter 的重计算。

现在main分支的最新版还存在这个问题吗

现在main分支的最新版还存在这个问题吗

有的， 比较容易复现（按问题描述里的配置方式修改 formily/antd/src/components/Card/preview.tsx）

这个 check 报错信息好像 main 上就有
