Sure, otherwise this would not be "ICE restart".

No. RTP packets may be lost during the transition, but SCTP protocol will ensure that datachannel packets are not lost.

I'm not sure whether performing ICE restart means dropping the previous `RTCIceTransport` and replacing it with a new one. If so, `RTCDtlsTransport.transport` should point to the new one.
