Extract mode fails with pitching loaders

What is the current behavior?
Looks like svg-sprite-loader using with sprite loader plugin in extract mode doesn't work with pitching loaders

If the current behavior is a bug, please provide the steps to reproduce, at least part of webpack config with loader configuration and piece of your code.
Create custom webpack loader with pitching logic. For example, I want to use require('picture.svg') to require picture-dark.svg and picture-light.svg and generate sprite by svg-sprite-loader.
Custom loader very basic example: here

It works fine when I try to return module.exports = require(${JSON.stringify(darkPictureRequest)}), but when I'm going to pass more than one file to the svg-sprite-loader with extract option enabled, my next.js page is in state of constant loading.
If I understand correctly, there is a similar problem when using extract-text-webpack-plugin, because its loader also uses pitching, so its hooks are called inside the svg sprite plugin.

How can you advise me to change the loader so that everything works correctly?
