Comment (by johnkleinschmidt):

 My original patch did display the visual feedback when an item is focused
 and expanded the submenus and allowed tabbing through them, but I noticed
 that if you kept on tabbing eventually you would get to the menus a second
 time, but they would not expand/navigate properly.  This was due to the
 fact that the wp-menu-image links did not have a tabindex on them and
 therefore were last in the tabbing order.  If these links are assigned a
 positive value tabindex, it messes up the tabbed navigation because you
 would have to tab twice to open the submenu.  Assigning these items a -1
 tabindex takes them out of the tabbing sequence completely.
