Wrong css order on production

[aerni]

• Laravel Mix Version: 1.7.2
• Node Version (node -v):
• NPM Version (npm -v):
• OS: maxOS Sierra 10.12.6

Description:

When using "npm run prod", the css output is different to "npm run dev" and "npm run watch". It puts the css classes in a wrong order. This might be related to CSS Output Order Differs between Production and Dev #815, get wrong css order after using HashedModuleIdsPlugin #5733, get wrong css order after using HashedModuleIdsPlugin #642

Steps To Reproduce:

It's hard to reproduce this, as I don't know myself when and why this happens. For now I just stumbled upon one style in my css that gets left out and overwritten by this issue. I can provide you with all my source files if needed.

I think it's related to the extract plugin. We're at their mercy until it's fixed. Nothing on the Mix end we can do, I don't think.
