setOrigin doesn't affect on physics center

Phaser 3
1

Hi,

When I try to change the origin of a sprite, I found the bounds of this sprite didn’t transform according to the sprite origin.

// my physics engine config
physics: {
        default: 'arcade',
        arcade: {
          debug: true,
          gravity: { y: 100 }
        }
}

// in game scene, I created a physic game object
this.bottom = this.physics.add.staticImage(0, this.height, 'rect');
this.bottom.setOrigin(0, 1);
this.bottom.displayWidth = this.width;
this.bottom.displayHeight = 140;

The following is the render result, you can see the bounds doesn’t transform according to your setting origin.

Is it the correct result? I hope the physics bounds can be transformed according to the settings.
Are there any other better ways to do this?

Thanks,
Atom
