ForkJoin not emit next if some of result is null

[acoshift]

var rx = require('rx')
var rxjs = require('rxjs')

var a = rx.Observable.forkJoin(
  rx.Observable.just(10),
  rx.Observable.just(20),
  rx.Observable.just(null),
  rx.Observable.just(40)
)

a.subscribe(
  r => console.log('Rx Next: ' + r),
  err => console.log('Rx Error: ' + err),
  () => console.log('Rx Complete')
)

var b = rxjs.Observable.forkJoin(
  rxjs.Observable.of(50),
  rxjs.Observable.of(60),
  rxjs.Observable.of(null),
  rxjs.Observable.of(80)
)

b.subscribe(
  r => console.log('Rxjs Next: ' + r),
  err => console.log('Rxjs Error: ' + err),
  () => console.log('Rxjs Complete')
)

Result

Rx Next: 10,20,,40
Rx Complete
Rxjs Complete

Yes, seems this is unexpected behavior, confirmed none of values are emit as suggested code snippet. Let me try to spend some time to triage this one.
