|TableView| Columns remain blank after adding rows

Columns that have been added while there is no rows remain blank after adding rows.
Manual resizing cause the column to show its content.

Test code:
import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
 
public class NewFXMain extends Application {
 
    private int rows = 0;
    private int cols = 0;
 
    public class TestDataClass {
 
        private final StringProperty testValue;
 
        public TestDataClass() {
            testValue = new SimpleStringProperty("value");
        }
 
        public TestDataClass(String s) {
            testValue = new SimpleStringProperty(s);
        }
 
        public String getTestValue() {
            return testValue.get();
        }
 
        public void setTestValue(String value) {
            testValue.set(value);
        }
 
        public StringProperty testValueProperty() {
            return testValue;
        }
    }
 
    @Override
    public void start(Stage primaryStage) {
        ObservableList<TestDataClass> list = FXCollections.observableArrayList();
        for (int i = 0; i < 4; i++) {
            list.add(new TestDataClass("val " + rows++));
        }
        TableView table = new TableView(list);
 
        TableColumn<TestDataClass, String> tableColumn = new TableColumn<>();
        tableColumn.setCellValueFactory(new PropertyValueFactory<>("testValue"));
        tableColumn.setText("col " + cols++);
        table.getColumns().add(tableColumn);
 
        Button rAdd = new Button("add");
        rAdd.setOnAction((evt) -> {
            list.add(new TestDataClass("val " + rows++));
        });
 
        Button rDel = new Button("remove");
        rDel.setOnAction((evt) -> {
            if (!list.isEmpty()) {
                rows--;
                int size = list.size();
                list.remove(size - 1);
            }
        });
 
        Button cAdd = new Button("add");
        cAdd.setOnAction((evt) -> {
            TableColumn<TestDataClass, String> col = new TableColumn<>();
            col.setCellValueFactory(new PropertyValueFactory<>("testValue"));
            col.setText("col " + cols++);
            table.getColumns().add(col);
        });
 
        Button cDel = new Button("remove");
        cDel.setOnAction((evt) -> {
            ObservableList columns = table.getColumns();
            if (!columns.isEmpty()) {
                cols--;
                int size = columns.size();
                columns.remove(size - 1);
            }
        });
       
        GridPane grid = new GridPane();
        grid.setVgap(3);
        grid.setHgap(3);
        grid.addRow(0, new Label("row:"), rAdd, rDel);
        grid.addRow(1, new Label("col:"), cAdd, cDel);
 
        VBox root = new VBox(table, grid);
        Scene scene = new Scene(root, 300, 250);
        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }
 
    public static void main(String[] args) {
        launch(args);
    }
 
}


Steps to reproduce:
1) remove all rows
2) add a column
3) try to add some rows
Column created on step 2 wont show its content, until you resize it manually.

Example with screenshots:
actions:
 remove all rows
 add a column
 add a row
 add a column
 remove row
 add a column
 add some rows
