when the build esm format file, Vue will be packaged as default export

[ShetePro]

First check https://github.com/SortableJS/Vue.Draggable/blob/master/CONTRIBUTING.md

Step by step scenario

When I use the plugin to package in esm format，The packaging result will contain import require$$0, { ... } from "vue";
Vue3x has no default export，This will cause a runtime error

Actual Solution

Expected Solution

not error

If use umd file, There will not be this problem.

Setting vue as an external dependency can solve this problem, but I don't know if there will be any other impact?

+1 same problem when using vite, got error:
No matching export in "node_modules/vue/dist/vue.runtime.esm-bundler.js" for import "default"

The compiled js file contains import _n, { ... } from "vue";
