Node lifetime question

I sat down to work on https://github.com/WebAudio/web-audio-api/issues/944
and discovered a question.

So: we already know (I think) that when AudioNode A's output is connected
to AudioNode B's input, then A has a "connection reference" to B. Thus, if
A is retained, B is retained too.

But what about the case where AudioNode A is connected to an AudioParam
exposed by AudioNode B? Does A keep B alive in this case?
