* Cover the penultimate uncovered line in OptionList Sort of moot, but worth a test that the control of a message is the option list. * Test OptionList hover over disabled option I *would* have liked to have tested this sort of thing via snapshot tests, but it seems that pilot.hover isn't quite behaving as desired there. But this provides a useful test anyway.
