Would you mind trying to bisect exactly where it happens?
I don't think any of the commits in that pull are supposed to change
semantics, and while reverting the whole merge shows that yes, that's
what brought in the problems, it would be good to pinpoint just which
change breaks so that we can fix just that thing.
