Comment (by dcf):

 Great work on this, cohosh. Missing data does seem to point to a bug in
 the pions implementation. backkem should be Cc'ed on this ticket so
 they'll get the report.

 My first guess is that the bug lies somewhere inside
 [https://github.com/pion/sctp pion/sctp]. As I understand it, a reliable
 dataconnection is SCTP inside DTLS. A working SCTP should make it
 impossible to drop a chunk of data.
