Is there a way to make images load in browser when using style-loader/css-loader?sourceMap without specifying absolute url prefix as publicPath?

With this loader:

loaders.push({
  test: /\.scss$/,
  loader: 'style!css?sourceMap')
});

This works:

output = {
  path: 'build',
  publicPath: 'http://0.0.0.0:8080/'
  filename: 'bundle.js'
};

This doesn't:

output = {
  path: 'build',
  publicPath: '/'
  filename: 'bundle.js'
};

In the CSS modules generated as Blob the paths are relative to chrome:blob or chrome:devtools which doesn't refer to the correct assets.

If my assumption is correct and we always have to set absolute path in output.publicPath I will be happy to add a note about this to the docs.
