Error type not propagated

[jbedard]

The webpack script loading error handling propagates the Error.type: https://github.com/webpack/webpack/blob/v4.8.3/lib/web/JsonpMainTemplatePlugin.js#L187-L192

Would be nice if the same was done for the css <link> load errors: https://github.com/webpack-contrib/mini-css-extract-plugin/blob/v0.4.0/src/index.js#L303-L309
