TextInputControl pseudo class state "readonly" is being set for editable fields

I was wanting to style non-editable fields with a slightly darker background so I went to look and see if there is a pseudo class state set for it. To my delight it looks like there is supposed to be a "readonly" state but it looks like the editable property falsely sets the state for editable fields instead of non-editable ones.

Line 294 in TextInputControl should probably read :

            pseudoClassStateChanged(PSEUDO_CLASS_READONLY, !get());

instead of:

            pseudoClassStateChanged(PSEUDO_CLASS_READONLY, get());

Here's a nice little test case that highlights the bug:

**************************************************************
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class FieldTest extends Application {

   @Override public void start(Stage primaryStage) throws Exception {

      primaryStage.centerOnScreen();
      primaryStage.setHeight(200);
      primaryStage.setWidth(400);

      TextField field1 = new TextField();
      field1.setEditable(false);
      field1.setEditable(true);
      field1.setText("Field is " + (field1.isEditable() ? "" : "not ") +
            "editable and pseudo states are: " +field1.getPseudoClassStates());
      
      TextField field2 = new TextField();
      field2.setEditable(false);
      field2.setText("Field is " + (field2.isEditable() ? "" : "not ") +
            "editable and pseudo states are: " +field2.getPseudoClassStates());
       
      primaryStage.setScene( new Scene( new VBox( 30, field1, field2 ) ) );
      primaryStage.show();

   }

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