### Enhancements

- `Draggable`: Render the drag clone inside the `@wordpress/ui` compat overlay slot so it shares stacking with `@wordpress/ui` overlays opened mid-drag. Auto-enabled in WordPress environments; other hosts can opt in via `useEnableWpCompatOverlaySlot()` ([#78183](https://github.com/WordPress/gutenberg/pull/78183)).
