(2) Dismissal of an appeal shall operate as an affirmance of the judgment being appealed if the appellate court so directs in the order of dismissal.
(3) If the parties to an appeal settle all or part of the matter on appeal, the trial court has jurisdiction to enter any orders or judgments that may be necessary to implement the settlement. If the settlement disposes of all issues on appeal, the appellate court may dismiss the appeal. If the settlement disposes of part of the issues on appeal, the appellate court may limit the scope of the appeal to the issues not disposed of by the settlement. [Formerly 19.111]
