When an entry module is itself a concatenated module, webpack-bundle-analyzer doesn't display the modules that are contained inside of the entry module in the report HTML. This is a regression from Webpack 4, where the concatenated modules would be included in the report graph.

pnpm install
pnpm run start

This will open two reports, one with webpack-bundle-analyzer@4.8.0 and one with the patched version of webpack-bundle-analyzer from webpack/webpack-bundle-analyzer#602.
