@pulkitkkr and I have been spending hours trying to debug why we get errors on ordering when splitting chunks.

Maybe the code should be updated to never worry about the ordering for CSS-modules automatically?

Is that the case where one is mixing some CSS modules and global CSS?

[alexander-akait]

I recommend to avoid it, except global styles like fonts/animations/counter styles/etc

What is "it" to avoid? mixing both modules and non-modules?

BTW, we owns https://github.com/shakacode/sass-resources-loader which allows global variables to be used within sass modules.

Yes, except global styels for all application, otherwise you need manually to check an order in many places
