Well, I looked through the git history from 9.3.9 to 9.3.11 and I don't
see anything that seems likely to explain a problem here.
If you can reproduce this, which it sounds like you can, maybe you could
create a self-contained test case for other people to try?
Also worth noting is that the current 9.3.x release is 9.3.14. You
might save yourself some time by updating and seeing if it still
reproduces in 9.3.14.
