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.

Simple reproduction: https://codepen.io/RationalCoding/pen/Qzwqrg?editors=0011
Comment 1 Thomas Mullen 2018-12-10 13:26:58 PST
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.
