Draggable objects break when restarting a scene

Description

Dragging an object works fine the first time the scene is created, but if you stop a scene and then start it again, you are no longer able to drag the object. I have tried both this.input.on() and gameObject.on() drag events.

Example Test Code

class Drag {
    create() {
        let image = this.add.image(50, 50, 'yes')
            .setInteractive();

        this.input.setDraggable(image);

        image.on('drag', function (pointer, x, y) {
            this.x = x;
            this.y = y;
        });
    }
}

Additional Information

Fix:
https://github.com/photonstorm/phaser/blob/master/src/input/InputPlugin.js#L2288
Change this line to

this._dragState = [ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ];
