This test checks that the ignorekeys attribute can be used on a menu to
disable key navigation. The test is performed twice by opening the menu,
simulating a cursor down key, and closing the popup. When keys are enabled,
the first item on the menu should be highlighted, otherwise the first item
should not be highlighted.
