Okay, I think I found it:
http://bugs.mysql.com/bug.php?id=47713
I added a comment with a link to a page I set up to show the behaviour on my
system.

:::: The raw milk movement provides a real solution to the problem of
food-borne illness -- because raw milk consumers make sure their milk comes
from small, pasture-based farms and healthy animals unlikely to harbor
pathogens and unlikely to contribute to water pollution, and because raw milk
builds immunity to disease-causing organisms that are simply a natural part of
the world in which we live. -- Ron Schmid
