Path Mapping is not properly work

[berlysia]

RxJS version:
6.0.0-alpha.3

Code to reproduce:

import { of } from 'rxjs';
import { map } from 'rxjs/operators';
import { ajax } from 'rxjs/ajax';
import { websocket } from 'rxjs/websocket';
import { TestScheduler } from 'rxjs/testing';

with webpack configuration for _esm5 described in doc/pipeable-operators.md#build-and-treeshaking

FYI: reproduced in webpack 3.11.0 & 4.0.0-beta.2

Expected behavior:
All import paths are mapped into _esm5 directory.

Actual behavior:
All import paths are mapped into root directory, not in _esm5.

Additional information:

import { of } from 'rxjs/index';
import { map } from 'rxjs/operators/index';
import { ajax } from 'rxjs/ajax/index';
import { websocket } from 'rxjs/websocket/index';
import { TestScheduler } from 'rxjs/testing/index';

works as expected.

Hi @berlysia !

As this is quite a while ago, is it probably already solved?

If yes please close that one. Otherwise please give a quick update of the current status.

This issue is already solved in v6.0.0 and also in v6.5.3. ✨
