[jitsi-dev] Odd 'packetsLost' behavior in video send stream

I've noticed the 'packetsLost' counter for my send ssrc seems to be
exhibiting some weird behavior: it jumps back and forth between a giant
value and 0 (see attached screenshot).

I haven't 100% verified yet, but I think I've only seen this behavior with
multiple downstream receivers. Is there something I might be doing that
causes the counter to get thrown off like this? Has anyone else seen this
issue in chrome?
