--bundle removes CSS ???

[RoyiNamir]

I've created an empty new project using tns create aaa --ng - Which is using Angular 5 & 3.40.

I've also added "nativescript-dev-webpack". the webpack.config.js file is the default one ( I havn't touched it). : https://gist.github.com/anonymous/4318d1205292d8707637f0b93cbd840a

The problem is that if I run : tns run android --env.uglify --env.report --env.aot - I do get to see the CSS in action :

But If I add --bundle : tns run android --bundle --env.uglify --env.report --env.aot I get to see this :

Question:

Why doesn't it respect the theme CSS ? It's a plain new project.

The sample project : https://ufile.io/bpkl8

BTw : all components uses ./ and added moduleid:module.id Just to see if that helps - still no.
Also platform remove/add didn't help.
