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

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.
