Inconsistent Objects between Dependency and Application Usage. 应用和依赖取到不同的对象

[kanocence]

Describe the bug

In APP.vue, a Page.vue(dependencies) component is referenced, and the getData function is executed in both components. This function is used to retrieve an object named data. However, after executing the getData function twice, the obtained data objects are different.The project created with 'Vue-cli' works well.

在APP.vue中引用了一个Page.vue(依赖中的)组件，并在两个组件中都执行了名为getData的函数。这个函数用来获取一个名为data的对象。然而，两次执行getData函数后得到的data对象却是不同的。vue-cli创建的项目没有这个问题。

dependencies:

let data = {}

export function setData (val) {
  data = val
}

export function getData () {
  return data
}

dependencies(Page.vue):

<script setup>
import { onMounted } from 'vue';
import { getData, setData } from './util';

onMounted(() => {
  console.log('vite-test-demo', getData());
  setData('vite-test-demo');
  console.log('getData', getData());
})
</script>

<template>
  <div>
    <h1>Page</h1>
  </div>
</template>

my app:

<script setup>
import { onMounted } from 'vue';
import { PageVue, getData, setData } from 'vite-test-demo';

onMounted(() => {
  console.log('vite getData', getData());
  setData('vite');
  console.log('vite getData', getData());
});
</script>

<template>
  <PageVue />
</template>

console:

vite-test-demo {}    ------> page.vue
getData vite-test-demo    ------> page.vue
vite getData {}    ------> app.vue
vite getData vite    ------> app.vue
