Description
我正在公司的组件库中封装Menu组件，是基于rc-menu进行的二次封装。现在有个逻辑是：在MenuItem被选中时，它所属的SubMenu的空心icon需要切换到选中态的实心icon，我发现在SubMenu中无法获取到它下属的MenuItem是否有被选中的。我尝试`import {PathUserContext} from 'rc-menu/lib/context/PathUserContext'，但在使用React.useEffect(PathUserContext)无法获取到值。请教下我该如何能实现上述的切换逻辑？

Research direction
Start by reading rc-menu/lib/context/PathUserContext and tracing how MenuItem and SubMenu use the context value. Reproduce the nested selection case described in the issue, then define and verify a supported way for SubMenu to know when a descendant MenuItem is selected and switch its icon accordingly.
