The module menu implements the keyboard navigation suggested by the ARIA Best Practices 1.1 for roles "menubar" and "menu". The first level menu has a "menubar" role, the second level submenus have a "menu" role. The buttons have the "menuitem" role. Both the "menubar" and the "menu" are oriented vertically for assistive technology matching the visual representation which affects the keyboard navigation. Space/Enter show the module unless the item has a submenu. Space/Enter and Right Arrow open a submenu and move focus to the first item. Up/Down Arrow and Home/End navigate within the current level of the menu. Ctrl + Home/End navigate within the first level of the menu (extension of the ARIA pattern). Left/Right Arrow moves to the parent item's predecessor/successor when on a submodule item. The submenu will not be closed (deviation from the ARIA pattern). Escape moves to the parent item of a submodule item. The submenu will not be closed (deviation from the ARIA pattern). Tab and Shift + Tab move to the next item outside of the module menu. The help menu implements the keyboard navigation suggested by the ARIA Best Practices 1.1 for the role "menu". This is the same as the module menu but limited to a single level. The change detaches again the module menu's event listener from the document as in #91642, but reinitializes the event listeners to handle situations as described in #93008 properly.
