      Description

      To reproduce:

      1. Click on Root item.
      2. Push Ctrl + PgDown (and other mentioned combinations) several times.

      Notice that when you push the combination for the first tine it works.
      But if you push the combination again nothing happens,
      and according to spec focus should move down one information pane.
      But now, selection or focused is not changing after the first time.

      public class TreeViewCtrlPgDown extends Application {

          }

          @Override

              Pane root = new Pane();

              TreeView<String> treeVeiw = new TreeView<>();

              treeVeiw.setPrefHeight(300d);
              
              TreeItem rootItem = new TreeItem("Root");
              rootItem.setExpanded(true);
              treeVeiw.setRoot(rootItem);

              for (int i = 0; i < 4; i++) {
                  TreeItem treeItem = new TreeItem("item-" + i);
                  treeItem.setExpanded(true);
                  rootItem.getChildren().add(treeItem);

                      treeItem.getChildren().add(childTreeItem);
                  }
