Comment 7 for bug 1695335

Menno: I just reproduced it on a Juju 2.3-alpha1.1 LXD controller using the test mentioned in comment #3 and captured all of the raw websocket frame data that the libjuju client saw: http://pastebin.ubuntu.com/25184849/

Note that `juju status` does show the right statuses, presumably since it's making a new API connection each time (which is also why we can work around this by issuing a FullStatus request), but no delta frame ever comes through with anything other than "pending" for "instance-status".
