A DESCRIPTION OF THE PROBLEM :
When a user clicks a text field the prompt text disappears. However this does not work when the CSS option -fx-prompt-text-fill: red; is used!

REGRESSION : Last worked in version 8u161

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The prompt text should be hidden when the text field is focused.
ACTUAL -
The prompt text is still shown.

---------- BEGIN SOURCE ----------
public class Main extends Application {

@Override
public void start(Stage primaryStage) throws Exception{
Stage stage = new Stage();
final TextField a = new TextField();
a.setPromptText("This is a prompt text");
a.setStyle("-fx-prompt-text-fill: red;");
VBox box = new VBox(0);
box.setMinWidth(0);
box.setFillWidth(false);
box.getChildren().addAll(a, new TextField());
stage.setScene(new Scene(box, 200, 200));
stage.show();
}


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

FREQUENCY : always
