This is extremely valuable information. I suspect we might have damaged
something in the backend code when inserting the mux layer. Given that
the connection and stream are a bit more independant from each other now
due to the mux, it might be possible that depending the sequence of some
events (eg: connection close), it changes how the close event is
interpreted in the stream. This will definitely help us narrow down the
cause of the issue.
