Auto import in Visual Studio Code only offering absolute path with Lerna subpackages in TypeScript

In Visual Studio Code, menu File → Preferences → Settings → User Settings,

"typescript.preferences.importModuleSpecifier": "relative"

It works fine for me. It imports

import { RegistrationComponent } from '../../abc-modules/registration/registration.component';

in place of

import { RegistrationComponent } from 'app/abc-modules/registration/registration.component';
