Every once in a while this comes up and we fix, e.g.

https://lore.kernel.org/git/528CE716.8060307@ramsay1.demon.co.uk/
https://lore.kernel.org/git/c6efda03848abc00cf8bf8d84fc34ef0d652b64c.1264151435.git.mhagger@alum.mit.edu/
https://lore.kernel.org/git/Koa4iojOlOQ_YENPwWXKt7G8Aa1x6UaBnFFtliKdZmpcrrqOBhY7NQ@cipher.nrlssc.navy.mil/
https://lore.kernel.org/git/20180713055205.32351-2-sunshine@sunshineco.com/
https://lore.kernel.org/git/574E27A4.6040804@ramsayjones.plus.com/

which is from a query

    https://lore.kernel.org/git/?q=one-shot+export+shell+function

but unfortunately we do not document which exact shell the observed
breakage happened with.

The closest article I found that is suitable as a discussion
reignitor talks about what POSIX requires, which may be more
relevant:
