sourceMapURL could not be parsed in Firefox

Sass source maps don’t work in Firefox when using yarn start.
I’ve read some old resources suggesting it could be the style-loader module that is generating the issue.

Resources I’ve fount:

It works as expected in Chrome though. Is this the same old issue, is there a fix yet?
