Could you give some minimal example?

Experiencing the same issue.

Config:

postcss({
    extract: true,
    minimize: true,
    plugins: [
        // Drops the preceeding '~' (needed for Storybook webpack loaders) &
        // removes intermediate dirs from font imports
        postcssUrl({
            filter: /\.(woff(2)?|ttf|eot|svg)(\?v=\d+\.\d+\.\d+)?$/,
            url: (asset) => `fonts/${asset.url.substr(1).split('/').pop()}`,
        }),
    ],
}),

My only CSS imports:

import '../app/styles/fonts/exo2/exo2.css';
import '../app/styles/fonts/iconfont/iconfont.css';
import '../app/styles/fonts/opensans/opensans.css';
