在useEffect中修改Set类型的state时，为什么要手动执行enableMapSet来允许呢？

[Highnesslin]

` const [state, setState] = useImmer({ listSet: new Set([]) });

useEffect(() => { setState(state => { state.listSet.add(activeRouteId); }); }, [activeKey]); Error: [Immer] The plugin for 'MapSet' has not been loaded into Immer. To enable the plugin, import and call enableMapSet() when initializing your application.`

import and call enableMapSet() from Immer when initializing your application.
