This bug has been discussed back in 2018 and a customer hit it few weeks ago
as well. Here is my last analysis, various link to histories, a workaround and a
even an humble patch proposal to discuss:
I even sent a patch to the ICU community to add a regression test exposing the
bug, but I had no answer.
Hopefully the workaround is good enough for you.
