10.2(EOL), 10.3(EOL)
Description
It seems to only affect 10.2 and 10.3. If it is indeed so, I don't expect it to be fixed, but I still need it be filed, so that we can ignore it in future.
The test case is non-deterministic. It currently fails for me on average within ~50 attempts, but it can vary a lot.

Another assertion failure happens on a much rarer occasion:
mysqld: /data/src/10.3/storage/innobase/btr/btr0scrub.cc:882: void btr_scrub_complete_space(btr_scrub_t*): Assertion `scrub_data->scrubbing' failed.

No coredump is produced in this case.
The data in the table is not required for the first failure, but might be necessary for the second one.
rr profile for the 1st failure is available.
