Review comment:
       No you're not missing anything, I was just looking at the wrong line! Yes, absolutely
agree - better now? However this actually now reveals a new real bug! See FINERACT-992...
do you happen to have any interest in taking that? Just asking! I'm marking this PR Draft
again after all, as we probably have to fix that issue before this can be merged.
