Cannot persist a chain tween after stop

Description

I expected that using the persist flag (true) on a chain tween would prevent it from being disposed of when stopped. The documentation mentions this behaviour, but I can't make it work.

Example Test Code

class Example extends Phaser.Scene 
{
    constructor()
    {
        super();
    }

    preload()
    {
        this.load.setBaseURL('https://cdn.phaserfiles.com/v385');
        this.load.image('block', 'assets/sprites/block.png');
    }

    create()
    {
        var marker = this.add.image(100, 300, 'block').setAlpha(0.3);
        var image = this.add.image(100, 300, 'block');

        var tween = this.tweens.chain({
            paused: true,
            persist: true,
            tweens: [{
                targets: image,
                x: 700,
                delay: 1000,
                duration: 6000,
                ease: 'Power2'
            }]
        });

        var toggle = false;
        this.input.on('pointerdown', function () 
        {
            if (toggle) {
                tween.stop();
            } else {
                tween.play();
            }
            toggle = !toggle;
        });
    }
}

const config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    backgroundColor: '#2d2d2d',
    parent: 'phaser-example',
    scene: Example
};

const game = new Phaser.Game(config);

I found this too. The doc says:

A Tween that persists will not be destroyed by the Tween Manager, or when calling Tween.stop, and can be re-played as required.

But calling the stop() destroys it.

As a workaround, you can use pause()/resume() instead of calling stop()/play(). It will work, if you change the input handler like this:

        this.input.on('pointerdown', function () 
        {
            if (toggle) {
                tween.pause();
                
            } else {
                if (tween.isFinished()){
                    image.x = 100;
                    tween.restart();
                } else {
                    tween.resume();
                }
            }
            toggle = !toggle;
        });
