Should setting an answer modify RTCRtpTransceiver.direction?

Here's an example to illustrate the point:

transceiver.setDirection("sendrecv");
// ...
pc.setLocalDescription(sendRecvOffer);
// ...
pc.setRemoteDescription(recvOnlyAnswer);
// What is transceiver.direction now? "sendrecv" or "sendonly"?

Has this question already been decided? If not, it's probably something we
should cover at the upcoming virtual interim.
