pjsua mwi problems: cseq ack problem

I'm seeing multiple problems with pjsua MWI handling. I've looked into where to fix it, but got lost in the layers of code and could use suggestions on where to focus my debugging.
I've seen this in both 1.8.5 and 1.8.10
Problem 1: apparently incorrect cseq on ACK of mwi notify
In this problem, the mwi subscription will sometimes get into a state where it will send ACKs with an incorrect cseq value, generally a cseq from the previous MWI notify.
This state continues (with broken MWI) until some other sip transaction occurs (such as a reregistration), which seem to clear the error state.
In the following pjsip output, you'll 1. notify with cseq 105 (notification of 2/4 new/old voice message) from asterisk (10.10.3.77) 2. correct 200 OK response with cseq 105 from pjsip (10.10.3.150) 3. notify with cseq 106
(1/5 new/old messages) 4. INCORRECT 200 OK response with cseq 105 (should be 106) 5. asterisk retries notify with cseq 106 6. INCORRECT 200 OK response with cseq 105 7.... asterisk retries about six more times, and keeps getting incorrect responses. 8. Asterisk eventually gives up retrying. We never get an on_mwi_info response.
Any suggestions would be very welcome.
