Flagrant system error loading a simple object

I have no problem loading https://wzrd.in/standalone/stylelint-config-standard@latest, which contains a `module.export` of a simple object.

But when I try to load a similarly simple object file https://wzrd.in/standalone/stylelint-config-recommended@latest, I get the flagrant system error shared below.

Both files have a similar structure:

* https://github.com/stylelint/stylelint-config-standard/blob/master/index.js
* https://github.com/stylelint/stylelint-config-recommended/blob/master/index.js

Oddly, when I load the same files through unpkg, the file structure is different in that the "stylelint-config-standard" doesn't include the `"use strict"` at the beginning of the file, but the "stylelint-config-recommended" file does include it.

* https://unpkg.com/stylelint-config-standard@1.0.0
* https://unpkg.com/stylelint-config-recommended@1.0.0

```

This is probably an issue with the package, and not browserify-cdn itself.

Reproduce the failure using the wzrd.in URLs and compare the linked index.js files for stylelint-config-standard and stylelint-config-recommended. Start with the reported npm install output; done means the recommended package loads successfully through wzrd.in without the flagrant system error.
