But in PostgreSQL 12, it works fine.

There may be some other stuff going on but your example relies on what is undefined behavior. That some particular outcome matches your expectation doesn’t make it correct.  That said, a similar nearby complaint suggests that this feature does have some issues.  Whether the version 12 behavior is deemed buggy and changed remains to be seen.
