Defect Fixes
Fixes #15110
The megamenu keyboard navigation was not working because the visibleItems kept returning the default processedItem rather than the items from the current processedItem. I removed the logic that was comparing the key with the focusedItem's parentKey. I don't know what that was doing but I manually tested the menu and also added a unit test.
It would be great to have all the unit test fixed so it'll be easy to tell if a change has broken something or not.
