Record user metric actions when the user opens the tab switcher while considered "engaged" with an in-product help promotion bubble. These metrics are only tracked when the user is considered "engaged" to help determine whether the promotion influenced the user to open the tab switcher. If the user has not seen the promotion or saw the promotion too long ago, the metric is not logged.
