Description Thomas Mullen 2018-12-10 13:25:51 PST 
RTCDataChannels that are created asynchronously will never open. This makes it impossible to create new channels later in the connection.

Chrome and Firefox have no such issue.

It should be noted that the channel is received by the remote peer (ondatachannel is fired). The channel just never opens and cannot send data.
