Failing to clean dummy-chunk on some occasions

Using webpack 4.x, svg-spritemap-webpack-plugin 3.3.5, Webpack configuration is something like this:

module.exports = {
    mode: "development",
    output: {
      path: path.resolve(context,"./dist"),
      filename: "code.bundle.js",
      //chunkFilename: "[id].js",
      publicPath: ""
    },
    plugins: [
      new SVGSpritemapPlugin('./editor/assets/svg/*.svg',{
        output: {
          filename: "symbol-defs.svg",
          svg4everybody: false
        },
        sprite: {
          prefix: "icon-"
        }
      })
    ]
}

If I define output.filename as a string without any placeholders, dummy module’s chunk uses that string as a postfix to define its filename. This causes the internal check to remove the dummy chunk fail.

compilation.chunks.forEach((chunk) => {
  if ( chunk.name !== outputOptions.chunk.name ) {
    return;
  }
  // chunk.name is 'spritemap' while chunk filename is 'spritemap.code.bundle.js' 
  chunk.files.filter((file) => {
    return [`${chunk.name}.js`, `${chunk.name}.js.map`].includes(file);
  }).forEach((file) => {
    delete compilation.assets[file];
  });
});

It can be easily fixed if you define a output.filename with placeholders or define output.chunkFilename. Latter is the one I preffered. Not sure if this is considered nitpicking.
