/**
|
|
* 回归用例：菜单管理 - 新建节点（未保存）→ 切到旧节点 → 切回新节点。
|
|
* 曾因 loadMenuConfig 用临时 id 查库返回空 → drafts = { menu: null }（真值）→
|
|
* 模板以 null menu 渲染 → render 抛错 → 在布局 <Transition> 下崩溃
|
|
* （表现为 "Component inside <Transition> renders non-element root node" +
|
|
* "Cannot set properties of null (setting '__vnode')"）。
|
|
* 修复：watch(menuSelectedId) 对未落库节点不走 loadMenuConfig，从树节点重建草稿。
