Version

3.0.0-beta.6

Reproduction link

https://github.com/batje/twocomponents

Steps to reproduce

• run npm install in the /component1 subfolder
• open the 'working.html' and 'failing.html' in your browser

The error will happing in the file failing.html (see your console)

What is expected?

If I have 2 webcomponent libraries with separate compiles, they should both work.

What is actually happening?

the second webcomponent generates an error and is invisible, because the first webpack_require instance is queried.

By adding the output.library option to the webpack config, each webcomponent library gets its own namespace.

This is implemented in component3 in the vue,config.js file , but should be standard, imho.
