  /** * Makes sure contextual links respond to mouseup event. * * Disabling interactive elements includes preventing defaults on the mouseup * event for links. However, this should not happen with contextual links. * This is confirmed by clicking a contextual link then moving the mouse * pointer. If mouseup is working properly, the draggable element will not * be moved by the pointer moving. * * @internal */
