* briefly unmount and remount while the drag is still active. If we're
* actively dragging, we should NOT end the pan session - it will
* continue tracking pointer events via its window-level listeners.
*
* The pan session will be properly cleaned up when:
* 1. The drag ends naturally (pointerup/pointercancel)
* 2. The component is truly removed from the DOM
