.buffer drops last buffer on source complete

[JaminFarr]

RxJS version: 5.0.0-rc.4

Code to reproduce:

const tick = Observable.interval(100).take(15)

tick.buffer(Observable.interval(1000))
  .subscribe((x) => console.log(x))

Expected behavior:

[0, 1, 2, 3, 4, 5, 6, 7, 8]
[9, 10, 11, 12, 13, 14]

Actual behavior:

[0, 1, 2, 3, 4, 5, 6, 7, 8]

Additional information:
Operators .bufferTime, .bufferCount, .bufferWhen and .bufferToggle all immediately emit any open buffers when the source completes. Operator .buffer does not. The lose of values is unexpected.

I would expect the results of the following to be the same

source$.buffer(closer$)
  .subscribe((x) => console.log(x))


source$.window(closer$)
  .mergeMap(x => x.toArray())
  .subscribe((x) => console.log(x)) // Outputs expected behavior

If this is confirmed as a bug I'd like to have a crack at fixing it
