The spec does not clarify how the `component` property is set. Should I assume the following?: - When creating a `RtcIceGatherer`via `var gatherer = new RtcIceGatherer()` its `component` will be 'RTP". - When creating a `RtcIceGatherer` via `gatherer.createAssociatedGatherer()` its `component` will be "RTCP". Am I right? If so, the spec should clarify it a bit more IMHO.
