Sourcemaps not working

[w4zZz4p]

I have created simple project which demonstrates the problem:
https://github.com/wazzzap/react-tests

If i set sourceMap for css-loader and less-loader final result is empty sourcemap.
If i disable sourceMap for less-loader i see only css sourceMap:
https://github.com/wazzzap/react-tests/blob/master/webpack.conf.js#L53

Reproduce the problem:

git clone https://github.com/wazzzap/react-tests.git
cd react-tests
npm install
npm start

Open browser http://localhost:9000 inspect the button. App.less shows empty content.
