That's the big question this unit test is trying to answer. (So: I'm not sure.)

Yes.

If that was the problem: all we needed to do is delete this call to `robot.mouseMove`.

(But even so: I think the cursor on Mac is black -- so why would we detect a gray 0x373737 ?)

It may also be worth pointing out: this test has never failed. It was added as an extra precaution, but not because it demonstrated a fix for anything. I would not miss it if we delete it; I don't think it deserves the time spent discussing/refactoring it.
