 Description   

Note: While it currently fails for me every time, the test case is still non-deterministic, try to run with --repeat=N if it doesn't fail for you right away.

Reproducible on 10.2-10.5 debug builds. Couldn't reproduce on 10.1, MySQL 5.6, 5.7, 8.0. No obvious effect on a non-debug build.

I can reproduce this with some iterations of

./mtr --parallel=auto --rr=-h MDEV-18802{,,,,,,,,,,,,,,,}; do :; done

The flag was cleared some time earlier:

I think that the easiest fix is to replace the assertion with an if and early return.
