Registry doesn't work when scenes start later

Description

So on the example on Scenes/Registry Data Exchange we have the registry that we can send data through scenes. The way i use to add scenes is following:

game.scene.add('PreloadScene', PreloadScene, true);
game.scene.add('PlayScene', PlayScene);

So in my example code i've removed active: true from scenes and started SceneB from SceneA. When we use scenes like this, registry and events doesn't work proparly.

Example Test Code

var SceneA = new Phaser.Class({
    Extends: Phaser.Scene,
    initialize: function SceneA() {
        Phaser.Scene.call(this, { key: 'SceneA' });
        this.score = 0;
    },
    create: function() {
        this.scene.start('SceneB');
        this.registry.set('score', this.score);
        this.time.addEvent({
            delay: 500,
            callback: this.onEvent,
            callbackScope: this,
            loop: true,
        });
    },
    onEvent: function() {
        this.score++;
        this.registry.set('score', this.score);
    },
});
var SceneB = new Phaser.Class({
    Extends: Phaser.Scene,
    initialize: function SceneB() {
        Phaser.Scene.call(this, { key: 'SceneB' });
        this.text;
    },
    create: function() {
        this.text = this.add.text(100, 100, 'Monitoring Registry');
        this.registry.events.on('changedata', this.updateScore, this);
    },
    updateScore: function(parent, key, data) {
        this.text.setText('Score: ' + data);
    },
});
var config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    backgroundColor: '#2d2d2d',
    parent: 'phaser-example',
    //scene: [SceneA, SceneB]
};
const game = new Phaser.Game(config);
game.scene.add('SceneA', SceneA, true);
game.scene.add('SceneB', SceneB);
