Reproducible on 10.2-10.5.
The test never runs anywhere, because it has an include file which requires innodb-page-size=4K, but the test doesn't have the option file, and the include file doesn't set it, it only checks the value. So the test always gets skipped.
The failure was revealed when I tried to do MDEV-21664, which makes these include files enforce the setting rather than just check it. So, it should be enough to fix the test itself without adding the opt file for it, after MDEV-21664 is pushed, the opt file won't be necessary.
