Example of bug in Phaser3 nested containers

PhaserNestedContainerBug.js

var config = {
    type: Phaser.AUTO,
    parent: 'phaser-example',
    width: 640,
    height: 480,
    scene: {
        create: create,
    }
};

var parentContainer, anotherParentContainer, childContainer;
var parentBounds, anotherParentBounds;
var graphics;

var game = new Phaser.Game(config);

function create ()
{
    graphics = this.add.graphics();

    parentContainer = this.add.container(128, 128);
    var circle = this.add.ellipse(0, 0, 128, 128, 0x00ff00);
    parentContainer.add(circle);

    var line = this.add.line(0,0,0,0,64,0, 0x0000ff);
    // line.setOrigin(0);
    childContainer = this.add.container(0, 0);
    childContainer.add(line);
    parentContainer.add(childContainer);

    anotherParentContainer = this.add.container(480, 256);
    var anotherCircle = this.add.ellipse(0, 0, 128, 128, 0x006600);
    anotherParentContainer.add(anotherCircle);

    var anotherLine = this.add.line(0,0,0,0,64,0, 0x0000ff);
    // line.setOrigin(0);
    anotherParentContainer.add(anotherLine);

    parentBounds = parentContainer.getBounds();
    anotherParentsBounds = anotherParentContainer.getBounds();

    graphics.clear();

    graphics.lineStyle(1, 0xff0000);
    graphics.strokeRectShape(parentBounds);

    graphics.lineStyle(1, 0xffff00);
    graphics.strokeRectShape(anotherParentsBounds);
