I've verified that this also affects Focal moving from the release pocket MySQL build (8.0.19-0ubuntu5) to the updates pocket (8.0.28-0ubuntu0.20.04.3) but with everything else fully up-to-date against the updates pocket.
I'm not sure what, if anything, we can do about this besides an upstream report, but I'm tagging it regression-update for statistics.
