WebAudio activeSourceCount

Question

Here's my code:

var ac = new webkitAudioContext();

On pressing the play button:

var source = ac.createBufferSource();
source.buffer = audioTrackBuffer;
source.connect(ac.destination);
source.noteOn(0);

On pressing the stop button:

source.noteOff(0);
source.disconnect();

Each time I press the play button ac.activeSourceCount increments.

Why doesn't activeSourceCount decrement when I noteOff() and disconnect() the source?

Looks like it was removed from the spec: https://dvcs.w3.org/hg/audio/rev/cfe4ae147c64

Basically, since they added the "ended" event, I think the idea is that you can keep track of this yourself now.
