Notes:
- The test case is non-deterministic, run with --repeat=N. It usually fails for me within several runs, but it can vary on different machines and builds.
- The first two lines in the test case are not necessary (it does not have to be InnoDB), the failure is reproducible with Aria and MyISAM, too; but it seems to take longer with MyISAM, and besides, the test case uses FOREIGN KEY at the end, so with InnoDB it is more meaningful.
- I do not know why ALTER .. FOREIGN KEY is important here and what its role is, especially when the test is run with MyISAM and Aria. But I couldn't get rid of it.

The failure started happening in 11.1 after a set of commits related to MDEV-7487 and MDEV-28883. The first buildable commit where I can reproduce it is
commit 554278e24dbc2c0af9fcfd66c54ca6a99a3cf17f
|
MDEV-7487 Semi-join optimization for single-table update/delete statements
|
but more likely it is related to
commit 3a9358a4106a1bd0ae2414f6f0bda50afdd65f0a
|
MDEV-28883 Re-design the upper level of handling UPDATE and DELETE statements
|
which I cannot build.
