JavaFX TextField cancelEdit 未按预期工作

I have a TextField https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TextField.html and I would like the contents of the field to be restored to their previous value when I press Esc which is expected behaviour on most systems (I have no idea why JavaFX doesn't do this by default).

为此我尝试使用TextField.cancelEdit() https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TextInputControl.html#cancelEdit--但似乎这没有做任何事情。

这是一个 SSCCE

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.input.KeyCode;
import javafx.stage.Stage;

public class UiTest2Controller extends Application {
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage aPrimaryStage) throws Exception {
        final TextField field = new TextField();
        field.setOnAction(aEvent -> {
            System.out.println("Action");
        });
        field.setOnKeyPressed(aEvent -> {
            if (aEvent.getCode() == KeyCode.ESCAPE) {
                System.out.println("Escape");
                field.cancelEdit();
                field.getParent().requestFocus();
            }
        });
        field.setPromptText("Hello World...");

        aPrimaryStage.setScene(new Scene(new Group(field)));
        aPrimaryStage.show();
    }
}

重现步骤：

1. 在文本字段中输入内容
2. Press Esc

预期行为：该字段返回到先前的值（第一次为空）并且焦点丢失。

实际行为：该领域保留了当时的价值，但焦点却消失了。

我不确定具体细节，但如果TextField has a TextFormatter分配：

field.setTextFormatter(new TextFormatter<>(TextFormatter.IDENTITY_STRING_CONVERTER));
