TestFX doesn't work when testing setOnKeyPressed on a Pane

I have a problem while testing a JavaFX application with TestFx. I put a sample, using just a VBox instead of a BorderPane that i use in real application. I just fill the pane with a canvas, to not have it empty, but with or without nothing changes.

public class MainPanelTest extends ApplicationTest {

    Pane toTest;
    boolean pressed = false;

    @Override
    public void start(Stage stage) {
        toTest= new VBox(new Canvas(800,800));
        toTest.setOnKeyPressed(e -> {
                     System.out.println("Pressed");
                     pressed = true;
        });
        stage.setScene(new Scene(toTest));
        stage.show();
        stage.toFront();
    }

    @Test
    public void test_keyPressed_D() {
        clickOn(toTest);
        press(KeyCode.D);
        WaitForAsyncUtils.waitForFxEvents();
        assertTrue(pressed);
    }
}

If instead of a Pane, I use a TextField for instance, all is working:

public class MainPanelTest extends ApplicationTest {

    TextField toTest;
    boolean pressed = false;

    @Override
    public void start(Stage stage) {
        toTest= new TextField();
        toTest.setOnKeyPressed(e -> {
                     System.out.println("Pressed");
                     pressed = true;
        });
        stage.setScene(new Scene(toTest));
        stage.show();
        stage.toFront();
    }

    @Test
    public void test_keyPressed_D() {
        clickOn(toTest);
        press(KeyCode.D);
        WaitForAsyncUtils.waitForFxEvents();
        assertTrue(pressed);
    }
}

Is there something that I'm missing here? In real application, when i press a key the event is catched correctly.

I figured out how to test it, it's needed to explicit request focus for the Pane. Simply adding this line toTest.requestFocus();.

This test pass:

public class MainPanelTest extends ApplicationTest {

    Pane toTest;
    boolean pressed = false;

    @Override
    public void start(Stage stage) {
        toTest= new VBox(new Canvas(800,800));
        toTest.setOnKeyPressed(e -> {
                     System.out.println("Pressed");
                     pressed = true;
        });
        stage.setScene(new Scene(toTest));
        stage.show();
        toTest.requestFocus();
    }

    @Test
    public void test_keyPressed_D() {        
        press(KeyCode.D);
        WaitForAsyncUtils.waitForFxEvents();
        assertTrue(pressed);
    }
}
