 * @class
 *
 * ### Overview
 * The `ui5-toolbar-item` is a wrapper component used to integrate UI5 Web Components into the `ui5-toolbar`.
 * It renders within the toolbar's shadow DOM and manages the lifecycle
 * and overflow behavior of its child component.
 *
 * ### Structure
 * The toolbar item wraps a single UI5 Web Component (such as CheckBox, Title, etc.) and handles:
 * - Overflow management (determining if the item should be displayed in the main toolbar or overflow popover)
 * - Automatic popover closing on interaction
 * - CSS custom state exposure for styling based on overflow state
 *
 * ### Usage
 * The `ui5-toolbar-item` is typically used implicitly when adding components to a toolbar,
 * but specialized wrappers like `ui5-toolbar-button` provide
 * component-specific functionality and should be preferred when available.
 *
 * @constructor
 * @extends ToolbarItemBase
