Embroider doesn't disable source map creation for vendor file

[Gorzas]

I'm currently trying to compile the webapp code without creating the source maps files in production. It's currently working for app code but not for vendor.js file (I understand that vendor file has the dependencies from the project). It doesn't matter if I change classic/broccoli configuration or I override Webpack's configuration, it still creates the source map for vendor.js file.

An example of what I have already tried:

module.exports = function (defaults) {
    sourcemaps: {
      enabled: false
    }
  });

  const { Webpack } = require('@embroider/webpack');
  return require('@embroider/compat').compatBuild(app, Webpack, {
    packagerOptions: {
      webpackConfig: {
        devtool: false 
      }
    }
});

This is an example of the dist/assets directory. The webapp files are created without source map as expected but it stills creates it for vendor file:

// ls -la dist/assets
chunk.123.js
chunk.456.js
vendor.css
vendor.js
vendor.css.map
**vendor.map**

I haven't dug deep enough into Embroider's code to know why this happens, so I'm not 100% sure this is an issue with Embroider. Could it be possible that source map configuration isn't passed down to vendor file compilation?
