Oops, yeah, the repro was wrong, I typed that line by hand instead of
copy/pasting. Sorry about that. On 10.12, with the correct line, do
you reproduce it still? Or was the bad line causing the issue for you?

If you can reproduce on 10.12, it may be a recent regression because I
hadn’t ever noticed it and I’ve been using it on 10.12 for a month or
two now at least.
