Import path not found in modern mode (now default mode)

Bug report

16.0.0 changes the path handling and the following code fails to import files:

                                {
                                    loader: 'sass-loader',

                                    options: {
                                        implementation: sass,
                                        api: 'legacy', //Note: needed or paths are not passed!!!
                                        //api: 'modern', //FIXME does not work (paths not found)

                                        sassOptions: {
                                            includePaths: themeBuilder.getSassIncludePaths()
                                        },

                                        additionalData: this.getSassVariables(themeBuilder)
                                    }

In order to get the path to work api has to be set to 'legacy'. Modern is not working.

apiType is here detected as modern:

And here no path is passed:

https://github.com/webpack-contrib/sass-loader/blob/c7ca4ee0bbd7303c29211593028b595d430e96ad/src/index.js#L69

Legacy mode passes the import paths here:

https://github.com/webpack-contrib/sass-loader/blob/c7ca4ee0bbd7303c29211593028b595d430e96ad/src/index.js#L65

How can we set the import paths in modern mode?

Actual Behavior

Import paths ignored in modern mode, the new default mode.

Expected Behavior

Import paths should be used.

How Do We Reproduce?

See examples above.
