Electron-webpack not watching files for symlinked angular library

I recently added an Angular library to my Angular project. I compile and symlink the lib into my node_modules folder for the main project.

Unfortunately, the compiled code is not triggering a rebuild of the main project.

I've tried many thing:

1. Watch options:

   watchOptions: {
         ignored: [
             // Ignore all node_modules, except my_module
             /node_modules([\\]+|\/)+(?!my_module)/,
             /my_module([\\]+|\/)node_modules/,
         ],
    },
   

2. monkeypatch watchpack

3. "preserveSymlinks": true in angular.json

4. Tried filewatcher-webpack-plugin:

   new filewatcherPlugin({
          watchFileRegex: [
             require.resolve('my_module')
          ]
   }),
   

   Result: When lib compiled, changes are detected and webpack crashes with "ConcurrentCompilationError: You ran Webpack twice."

5. Tried webpack-watch-files-plugin

   new WatchExternalFilesPlugin({
        files: [
            './dist/my_module/bundles/my_module.umd.js'
        ],
        verbose: true
   })
   

   Result: Correctly logs "Additional files watched: [file path]", but does not trigger compilation when the symlinked library is compiled.

6. Tried extra-watch-webpack-plugin

   new ExtraWatchWebpackPlugin({
       files: [
          './node_modules/uikit/fesm2015/mymodule.js'
       ]
   }),
   

I'm running out of ideas here.
