Why don't all styles come from the package?

Question

JavaScript

Hello!

I ran into a problem that styles, namely media queries, do not reach from the installed package. In other projects everything works correctly.

Style settings in webpack config

const getStyleLoaders = (cssOptions, preProcessor) => {
    const loaders = [
      isEnvDevelopment && require.resolve('style-loader'),
      isEnvProduction && {
        loader: MiniCssExtractPlugin.loader,
        options: paths.publicUrlOrPath.startsWith('.')
          ? { publicPath: '../../' }
          : {},
      },
      {
        loader: 'css-loader',
        options: cssOptions,
      },
      {
        loader: 'postcss-loader',
        options: {
          sourceMap: isEnvProduction && shouldUseSourceMap,
        },
      },
    ].filter(Boolean);
    if (preProcessor) {
      loaders.push(
        {
          loader: require.resolve('resolve-url-loader'),
          options: {
            sourceMap: isEnvProduction && shouldUseSourceMap,
          },
        },
        {
          loader: require.resolve(preProcessor),
          options: {
            sourceMap: true,
          },
        }
      );
    }
    return loaders;
  };

{
              test: /\.css$/,
              use: getStyleLoaders({
                importLoaders: 1,
                sourceMap: isEnvProduction && shouldUseSourceMap,
              }),
              sideEffects: true,
            },
            {
              test: /\.pcss$/,
              use: getStyleLoaders({
                importLoaders: 1,
                sourceMap: isEnvProduction && shouldUseSourceMap,
                modules: {
                  getLocalIdent: getCSSModuleLocalIdent,
                },
              }),
            },

I would be grateful for any hint. Thank you!
