Backspacing a newline character hides the previous line

[JordanMartinez]

Run the following code:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.stage.Stage;
import org.fxmisc.richtext.InlineCssTextArea;
import org.fxmisc.richtext.NavigationActions;

public class BugIssue extends Application {

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

    @Override
    public void start(Stage primaryStage) {

        InlineCssTextArea area = new InlineCssTextArea("Hello there");
        primaryStage.setScene(new Scene(area, 400, 400));
        primaryStage.show();

        area.lineEnd(NavigationActions.SelectionPolicy.CLEAR);
        area.requestFocus();
    }
}

Then do the following steps

1. press enter key
2. press backspace key

You will see the first line is now hidden. If you type anything after that, the line will reappear.

No doubt this bug is introduced somehow with the new WellBehavedFX release.

Actually, I can confirm the bug first arises when 420ba08 is checked out.
