(Core :: Web Audio, defect)

Steps to reproduce:

1. Setup an audio source with a gain node using Web Audio API.
2. Fade to wanted value using this code: 
	var now = context.currentTime;
	this.volume.gain.linearRampToValueAtTime(this.volume.gain.value, now);
	this.volume.gain.linearRampToValueAtTime(fGain, now+fTime);



Actual results:

this.volume.gain.value does not update during the fade, it's always stuck at 1. 
It works when fading down, but not up.


Expected results:

this.volume.gain.value should update to the current value as the ramp is fading. 
this is how it works in chrome and safari, My guess is that this should be the implementation.
