 *
 * ### Overview
 * The `ui5-li-notification-group` is a special type of list item,
 * that unlike others can group items within self, usually `ui5-li-notification` items.
 *
 * The component consists of:
 *
 * - `Toggle` button to expand and collapse the group
 * - `TitleText` to entitle the group
 * - Items of the group
 *
 * ### Usage
 * The component should be used inside a `ui5-notification-list`.
 *
 * ### Keyboard Handling
 * The `ui5-li-notification-group` provides advanced keyboard handling.
 * This component provides fast navigation when the header is focused using the following keyboard shortcuts:
 *
 * - [Space] - toggles expand / collapse of the group
 * - [Plus] - expands the group
 * - [Minus] - collapses the group
 * - [Right] - expands the group
 * - [Left] - collapses the group
 *
