To reproduce: run example, double-click into combo cell to open drop-down

- press up (or down) to navigate to another item
- expected: drop-down still open and editing
- actual: drop-down closed and edit committed

choice behaves as expected

The example:

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.ChoiceBoxTableCell;
import javafx.scene.control.cell.ComboBoxTableCell;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.BorderPane;
import javafx.scene.shape.*;
import javafx.stage.Stage;

public class ComboChoiceCellIssues extends Application {

    private Parent getContent() {
        ObservableList<Shape> items = FXCollections.observableArrayList(
                new Line(), new Rectangle(), new Arc());
    
        TableView<Shape> table = new TableView<>(items);
        table.setEditable(true);
        TableColumn<Shape, StrokeType> plain = new TableColumn<>("Plain");
        plain.setCellValueFactory(new PropertyValueFactory<Shape, StrokeType>("strokeType"));
         
        TableColumn<Shape, StrokeType> combo = new TableColumn<>("Combo");
        combo.setCellValueFactory(new PropertyValueFactory("strokeType"));
        combo.setCellFactory(ComboBoxTableCell.forTableColumn(StrokeType.values()));
         
        TableColumn<Shape, StrokeType> choice = new TableColumn<>("Choice");
        choice.setCellValueFactory(new PropertyValueFactory("strokeType"));
        choice.setCellFactory(ChoiceBoxTableCell.forTableColumn(StrokeType.values()));
         
        table.getColumns().addAll(plain, combo, choice);
         
        Parent content = new BorderPane(table);
        return content;
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        primaryStage.setScene(new Scene(getContent()));
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
