Webpack5 + MiniCssExtractPlugin + html-webpack-plugin not add link tag on index.html

Question

I try to build in production with Webpack5 + MiniCssExtractPlugin + html-webpack-plugin and other plugins but i'm not able to have css tag included in index.html.

Every time css files are append by javascript with "flash of unstyled content" (FOUC) problem.

I use npm run build with this easy command: webpack --config webpack.prod.js

webpack.prod.js

const path = require('path');
const common = require('./webpack.config');
const { merge } = require('webpack-merge');
const {CleanWebpackPlugin} = require('clean-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = merge(common,{
    mode: 'production',
    output: {
        path: path.resolve(__dirname, 'build'),
        publicPath: '',
        filename: '[name].[hash].js',
    },
    plugins: [
        new CleanWebpackPlugin({}),
        new MiniCssExtractPlugin({
            filename:'[name].[hash].css'
        })
    ],
    module: {
        rules: [
            {
                test: /\.css$/i,
                use: [
                    MiniCssExtractPlugin.loader,
                    'css-loader'
                ]
            },
            {
                test: /\.scss$/i,
                use: [
                    MiniCssExtractPlugin.loader,
                    'css-loader',
                    'sass-loader'
                ]
            }
        ]
    }
});

webpack.config.js

const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
    entry: {
        index: './src/index.js',
        vendor: './src/vendor.js'
    },
    plugins: [
        new HtmlWebpackPlugin({
            inject: 'body',
            template: './src/index.html',
            scriptLoading: "defer"
        })
    ],
    module: {
        rules: [
            {
                test: /\.html$/,
                use: [{
                    loader: 'html-loader'
                }]
            },
            {
                test: /\.(png|jpe?g|gif)$/i,
                use: [{
                    loader: 'file-loader',
                    options: {
                        name: '[name].[ext]',
                        outputPath: 'assets/images/'
                    }
                }],
            },
            {
                test: /\.(woff(2)?|ttf|eot|svg)(\?v=\d+\.\d+\.\d+)?$/,
                use: [{
                    loader: 'file-loader',
                    options: {
                        name: '[name].[ext]',
                        outputPath: 'assets/fonts/'
                    }
                }]
            }
        ]
    }
};

and this is the index.html result:

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="msapplication-tap-highlight" content="no"/>
    <title>title</title></head>
<body>

 all code here... 
 
<script defer="defer" src="index.19fae54ea5525bb23f67.js"></script>
<script defer="defer" src="vendor.19fae54ea5525bb23f67.js"></script>
</body>
</html>

and inside the build folder i have a list of *.js and *.css files with hash and assets folder with his content.

Thank you for help
