Yeah this is because the dist folder structure. We need to tweak the folder after the build, before serve. It could be nice if we have a way to handle this.

Why isn't it considered as a bug?

Documentation suggests the following structure

and the following scripts

Developers do what Documentation says and it doesn't work: docs:serve script doesn't work.
