react-scripts 3.3.0: Grids do not get autoprefixed for IE11 in production builds using sass modules

Created by: chce

Describe the bug

CSS isn't getting autoprefixed when using Sass modules. Not sure if it's also the case for css. This breaks the styling for IE11.

Did you try recovering your dependencies?

Yes

Which terms did you search for in User Guide?

I tried to figure out how to give some custom options to the build process to see if that could fix it, I guess?

Environment
