preprocessCss is no longer run on composed files

[willdawsonme]

Since css-modules-require-hook started using postcss-modules-resolve-imports (v4.2.2), preprocessCss is no longer being called on composed files, which makes using this module with stylus impossible if you use composes.

For example, this:

// src/components/Home/styles.styl
.header
    composes: header from '../styles/page.styl'

should give me:

// src/components/Home/index.js
styles = {
    header: 'styles__header__abcd page__header__abcd',
}

but instead I get:

// src/components/Home/index.js
styles = {
    header: 'styles__header__abcd header',
}

because page.styl isn't being preprocessed before postcss is run.

Finally! that's the crux of the matter I've been struggling with for 2 days... Thanks @willdawsonme!

My setup runs exclusively on .scss modules, but the reason it fails is the same - no call on composed files, as mentioned above.
Had to resort to 4.2.1 to make it work.

Perhaps it wouldn't be the case if it was different setup. In my case it's modules nesting that produce such results.

P.S. I use require hook only for testing purposes.

If anybody is still interested, I presumably fixed this in my fork of the library, published to NPM: https://www.npmjs.com/package/@dr.pogodin/css-modules-require-hook
