Importing vue.min.js inside es6 module doesn't work

Version

2.5.21

Reproduction link

Steps to reproduce

Simply import vue.min.js with es6 import instead of inside a script tag

What is expected?

Vue should load as window.Vue and be available inside the page

What is actually happening?

Since inside modules windows != this (this is undefined) umd loading fails

---

This bug would be easily fixed replacing this with this || self in umd header.

Also refer to umdjs/umd#124

That build is not meant to be consumed in a module setup.

Why don't use the esm build? If you ineed Vue on window, assign it yourself.

Use esm build:

import Vue from 'https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.21/vue.esm.browser.min.js'

2.6 will include dist/vue.esm.browser.min.js which is meant for direct ES6 import.

Hi!
Thanks for your answers.
I've already tried the vue.esm.browser.min.js, but it doesn't solve my problems either.
The same page works with the script tag and with with the "|| self" patch, but it doesn't with the browser es6 version: the page loads but reactivity is broken.
Exactly same code; the same issue happens both with source code and after rollup build.
Am I missing something or should I open a new issue?
I'll add a codepen as soon as possible.

Seems like a sparate issue.
