I'd expect the following to produce the same result:

        TextField textfield2 = new TextField("textfield2");
        textfield2.setStyle("-fx-font: \"Courier New\"; -fx-font-size: 22pt;");
        
        TextField textfield3 = new TextField("textfield3");
        textfield3.setStyle("-fx-font-size: 22pt; -fx-font-family: \"Courier New\";");

However textfield2 is getting default font. See screenshot.
