The node_modules/test_atom is only referenced in entry.js but nothing is done with it.
I'm curious to know how exactly do we reference the css of an atom once it is in the node_modules directory.
Can you update the example (eg in your ui/entry.css, do you @import test_atom/style.css?). Kind of unsure how the package.json's style field plays into this.
Also does it work if the style field is less instead of a css file?
