this is the tableCell variant of JDK-8145588 - isn't it supposed to be fixed for all descendants of Cell (where it was fixed)?

Anyway, to reproduce, run the example below as-is and select a cell
- expected: cell content is prefixed by "winner!!)
- actual: cell content unchanged

the reason seems to be the same as in the referenced old bug - at least it can be hacked-around in a similar way: override updateSelected and call updateItem manually (uncomment the method in the example below)

Please make sure to fix it for _all_ cell types ;)

the example:

public class TableCellContentOnSelection extends Application {

    private Parent createContent() {
        ObservableList<Locale> data = FXCollections.observableArrayList(
                Arrays.stream(Locale.getAvailableLocales(), 10, 20).collect(Collectors.toList()));
        TableView<Locale> table = new TableView<>(data);
        table.getSelectionModel().setCellSelectionEnabled(true);
        table.getColumns().addAll(createTableColumn("displayLanguage"));
        return new BorderPane(table);
    }

    private <T> TableColumn<T, String> createTableColumn(String property) {
        TableColumn<T, String> column = new TableColumn<>(property);
        column.setCellValueFactory(new PropertyValueFactory<>(property));
        column.setCellFactory(cc -> {
            // custom cell with text depending on selection state
            TableCell<T, String> cell = new TableCell<>() {

                @Override
                protected void updateItem(String item, boolean empty) {
                    super.updateItem(item, empty);
                    if (item == null || empty) {
                        setText("");
                    } else {
                        if (isSelected()) {
                            item = "winner!! " + item;
                        }
                        setText(item);
                    }
                }
