Thanks for the excellent reproducer for this obscure bug. You said
the problem exists in 9.6-11, but I'm also able to reproduce it in
9.5. That's the oldest supported release, but it probably goes back
further. I confirmed that this patch fixes the immediate problem.
I've attached a version of your patch with a commit message, to see if
anyone has more feedback on this.
