Steps to reproduce

<Suspense>内含有嵌套路由，且使用了异步组件时。 当页面内的异步未执行结束时路由跳转，会发生错误。

// App.vue
<div>
  <router-link to="/">routerA</router-link>;&nbsp;
  <router-link to="/pageB">routerB</router-link>
</div>

<RouterView v-slot="{ Component }">
  <template v-if="Component">
    <Suspense>
      <component :is="Component" />
    </Suspense>
  </template>
</RouterView>

// router/index.js
...
routes: [{
  path: '/',
  component: Layout,
  children: [...pageA.vue,pageB.vue]
}]

// Layout.vue
<template>
  <router-view />
</template>

// pageA.vue ,pageB.vue
<script setup>
await new Promise((resolve) => {
  setTimeout(() => resolve(), 5000)
})
</script>

What is expected?

跳转正常

What is actually happening?
