[webrtc-pc] [Question] Is it guaranteed that the mid property value of transceiver is the same for sender and receiver? (#2527)

gtk2k has just created a new issue for https://github.com/w3c/webrtc-pc:

== [Question] Is it guaranteed that the mid property value of transceiver is the same for sender and receiver? ==
I wrote the code.

[gist](https://gist.github.com/gtk2k/00f8c6473372a00a6302692242206bc2)

Video elements are selected and displayed based on their mid property value, but if the transmitter changes the order in which transceivers are created, the receiver mids will no longer match.
