Webpack, why doesn't LiveReload work on HTML changes if Hot Module Replacement is enabled?

Question

Building projects

If you set hot: true in Webpack 's devServer settings , then Hot Module Replacement for CSS works and changes are applied without a full page reload. But for some reason, when changing HTML files , LiveReload does not work , you need to update the page manually for the changes to be applied. If you disable hot: true in the configuration file in devServer , then when changing HTML files, LiveReload works fine, the page reloads itself, but Hot Module Replacement for CSS does not work

, when you change the CSS , the page reloads completely.

Is this behavior supposed to be? Why is this happening, how can you enable Hot Module Replacement for CSS , but still have LiveReload working when changing HTML files? I use the HtmlWebpackPlugin

plugin to generate multiple HTML files . Here are the config files below: webpack.common.js

const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyPlugin = require('copy-webpack-plugin');
const webpack = require('webpack');

module.exports = mode => {
const PRODUCTION = mode === 'production';

return {
    entry: {
        app: './src/index.js',
    },
    output: {
        filename: 'js/[name].bundle.js',
        path: path.resolve(__dirname, 'dist'),
        publicPath: '/',
    },
    module: {
        rules: [
            {
                test: /\.(png|jpe?g|gif|svg)$/i,
                use: [
                    {
                        loader: 'file-loader',
                        options: {
                            name: 'img/[path][name].[ext]',
                            outputPath: 'img',
                        },
                    },
                ],
            },
        ],
    },
    plugins: [
        new CleanWebpackPlugin(),
        new HtmlWebpackPlugin({
            hash: false,
            template: 'src/index.html',
            filename: 'index.html',
        }),
        new webpack.DefinePlugin({
            PRODUCTION: PRODUCTION,
        }),
        new CopyPlugin([
            { from: 'src/img', to: 'img' },
            { from: 'src/fonts', to: 'fonts' },
        ]),
    ],
}
};

Try to include html-loader and include index.html to index.js file (import './index.html')
