            // where a task is NOT organized but had its visibility changed within its direct

            // parent. An example of this is if an alternate home leaf-task HB is started atop the

            // normal home leaf-task HA: these are both in the Home root-task HR, so there will be a

            // transition containing HA and HB where HA surface is hidden. If a standard task SA is

            // launched on top, then HB finishes, no transition will happen since neither home is

            // visible. When SA finishes, the transition contains HR rather than HA. Since home

            // leaf-tasks are NOT organized, HA won't be in the transition and thus its surface

            // wouldn't be shown. Just show is safe here since all other properties will have

            // already been reset by the original hiding-transition's finishTransaction (we can't

            // show in the finishTransaction because by then the activity doesn't hide until

            // surface placement).
