Is there anyone here who can reproduce this problem?

I can't (and will not be able to) test on NetBSD 9.99.
I tested on NetBSD 9.3, but couldn't reproduce the problem.

I also tested on FreeBSD 13.1, but ^Z/fg worked fine.
I don't have Ubuntu-19.04, but any of LTS (18.04/20.04/22.04) works fine.
Does the problem occur every time you suspend a pipeline, or just
occasionally? (I tested only a few times)

I'm testing on virtual machines for which I allocate only two CPU cores.
Usually two cores are enough to reproduce this kind of problems (probably
related with a kind of race conditions), but haven't tested with more cores.

Can you try 'git bisect'?
Or at least checkout some specific commits (the one just before the
suspicious commits) and test them?
