as pointed out in a private conversation: we have a patch sitting on
Jeremy's laptop. To be honest, I already forgot about the details, just
remember sitting together with Jeremy banging our heads against this for
2-3 ours until we found the root cause. Iirc what's missing is a test
for CI and due to lack of time, this is still sitting in the backlog.
