同一个store无法再多个vue实例使用(Reactivity is not work in multiple Vue instance)

[gonlyk]

我在写一个undostack功能，想在开发阶段通过createApp创建一个新的vue实例来显示当前的undostack状态，但响应式并没有生效

if (process.env.NODE_ENV === 'development') {
    window.onload = function () {
        // @ts-ignore
        // globalThis.undoStack = useUndoStack().undoStack
        const stackView = document.createElement('div')
        stackView.style.position = 'absolute'
        stackView.style.overflow = 'auto'
        stackView.style.height = '200px'
        stackView.style.width = '200px'
        stackView.style.bottom = '0'
        stackView.style.left = '0'
        stackView.style.border = '1px solid black'
        document.body.appendChild(stackView)
        setTimeout(() => {
            createApp(defineComponent({
                setup() {
                    const undoStack = useUndoStack()
                    const count = ref(0)
                    console.log('undoStack.undoStack.stack', undoStack)
                    // didn't rerender when stack change
                    return () => h('div', undoStack.undoStack.stack.map(item => h('div', [item.id])).concat(
                        h('button', { onClick: () => { count.value += 1 } }, [count.value])
                    ))
                }
            })).use(createPinia()).mount(stackView)
        }, 500)
    }
}

其中undoStack.undoStack.stack是一个list，例子中的count响应式生效了而stack没有
