https://aa.cbddev.xyz/ie/loads-same-monorepo-lib-one.html
https://aa.cbddev.xyz/ie/loads-same-monorepo-lib-two.html

What is expected?

That there be no webpack conflicts and each umd should load and be present on the window object in IE11.

What is actually happening?

error: Out of stack space - not clear where from IE
first umd loads second does not.

---

Each used alone is ok, however, together it results in stack overflow. If one was built with vue cli 3 again ok. Everything is fine in other browsers.

I tried to add output.uniqueName to webpack config for each but 'uniqueName' was not permitted on build error was given on vue-cli-service build command.

Working on that. There's a bug in this dependency: https://github.com/sodatea/get-current-script

I've figured out the fix but need more testing. If the tests passed I'll release a new version in hours.

Fixed in @soda/get-current-script v1.0.1
