Reproducible on 10.5+, but on some reason not on 10.2-10.4.
The failure has some relation to MDEV-26220, but due to the complicated history of the bugfix I can't find out whether it fixed the problem in 10.2-10.4 but not in 10.5, or introduced the problem in 10.5, or something else happened.

Critical
