 By default, Webpack uses `output.library` as the namespace for module
 source maps, which generates the URL `webpack://wp.[name]/<path of
 module>`. This loads fine in Chrome, but in Firefox it throws an error
 similar to:


   Source map error: TypeError: Invalid URL:
 webpack://wp.[name]/webpack/bootstrap
   Resource URL: http://localhost:8888/wp-
 content/plugins/gutenberg/build/components/index.js?ver=1565639281
   Source Map URL: index.js.map

 The solution to this is to specify a
 [https://webpack.js.org/configuration/output/#outputdevtoolnamespace
 devtoolNamespace].

 So for example, setting `devtoolNamespace`to `wp` would result in the URL
 `webpack://wp/<path of module>` (which the attached patch does).
