/**
* `<lr-dropdown-item>` — the Web Awesome-compatible name for a menu item.
* It is intentionally a subclass of `<lr-menu-item>`, so it participates in
* the same roving focus, checkbox, radio, selection, and menu event contracts — and
* in the same `size` ladder, including the `small`/`medium`/`large` spellings.
* It also inherits `<lr-menu-item>`'s `href`/`target`/`rel`/`download` link-item support, mirroring
* `wa-dropdown-item`'s identical navigation surface — see that class's doc.
*
* @customElement lr-dropdown-item
* @slot - The item's visual label content. Its flattened subtree is inert and hidden from assistive
*   technology; its accessible text names the host menu item.
* @slot icon - Optional decorative leading icon. Its flattened subtree is inert and hidden from
*   assistive technology.
* @slot prefix - Shoelace-compatible decorative alias for leading content. Its flattened subtree is
*   inert and hidden from assistive technology.
* @slot details - Decorative WA-compatible secondary detail text. Its flattened subtree is inert and
*   hidden from assistive technology.
* @slot suffix - Shoelace-compatible decorative trailing content. Its flattened subtree is inert and
*   hidden from assistive technology.
* @slot submenu - A nested `<lr-menu>` or direct mapped dropdown items that open beside this row.
* @event focus - Native, non-bubbling, composed, non-cancelable `FocusEvent` emitted by the
* focusable host when it gains focus.
* @event blur - Native, non-bubbling, composed, non-cancelable `FocusEvent` emitted by the
* focusable host when it loses focus.
* @attr {boolean} submenuopen - Normalized Web Awesome compatibility alias for `submenu-open`;
*   both spellings reflect the live submenu state and changing either spelling controls it.
* @csspart base - The visual item row.
* @csspart checkmark - WA-compatible checkbox glyph.
* @csspart checked-icon - Shoelace-compatible checkbox-glyph wrapper.
* @csspart icon - Leading icon wrapper.
* @csspart prefix - Shoelace-compatible leading-content wrapper.
* @csspart label - Label wrapper.
* @csspart details - WA-compatible detail wrapper.
* @csspart suffix - Shoelace-compatible trailing-content wrapper.
* @csspart spinner - Loading spinner.
* @csspart spinner__base - Shoelace-compatible spinner alias.
* @csspart submenu-icon - Submenu chevron wrapper.
* @csspart submenu - Submenu panel/wrapper.
* @cssprop --lr-overlay-surface - Shared floating-surface fill. Advertised here because this tag
*   shares a stylesheet directory with `lr-menu`, whose surface reads it; a dropdown item is a row
*   inside that surface and paints no surface of its own, so setting it here changes nothing.
* @cssprop --lr-overlay-border - Shared floating-surface edge colour, with the same deliberate
*   exclusion as `--lr-overlay-surface` above.
* @cssprop --lr-overlay-radius - Shared floating-surface corner radius, with the same deliberate
*   exclusion. The row's own corners come from `--lr-menu-item-radius`.
* @method openSubmenu - Opens the submenu and resolves after its open state settles.
* @method closeSubmenu - Closes the submenu and resolves after its closed state settles.
* @status stable
* @since 4.0.0
