Let's see if I read this discussion correctly:

1. We don't support macOS older than 10.10.  (Perhaps that should be
   10.11 once 10.15 is released in October?)

2. This bug doesn't manifest itself on macOS 10.10 or later.

So is there anything left to do here?  If the above two points are true,
then I guess this should be closed as wontfix?
