Reproducible on 5.1.4 too
Interesting. The root cause of this problem has existed since June, 2012,
when I first added namerefs. When I went looking for the reason it seemed
to work in bash-4.4 but not bash-5.0, I discovered it was masked until
March, 2017, so it `worked' in bash-4.3 and bash-4.4, until that dependency
was fixed.
I agree that it should work -- there doesn't seem to be any reason it
shouldn't -- so I will make it work again in the next devel branch push.
