To reproduce, run example,

- double-click cell in combo column to start edit, drop-down opens
- click selected (= old) value or press enter
- expected: edit committed, that is combo removed
- actual: drop-down closed, combo still visible

similar for choice cell

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("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.setTitle(FXUtils.version());
        primaryStage.show();
    }

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