Default component values are the same object?

[esromneb]

It seems like default values of components are actually the same (Warning I'm on an old release 609c511)

I have this component:

export class UnitBuildQueue extends Component {
static properties = {
    queue: [],
    frameAdded: 0,
  };
};

I have this code:

let e0, e1; // two entities initialized elsewhere
e0.addComponent({
  type: 'UnitBuildQueue',
  key: 'q',
  frameAdded: 10,
});


e1.addComponent({
  type: 'UnitBuildQueue',
  key: 'q',
  frameAdded: 20,
});

e0.c.q.queue.push('foo');

console.log(e1.c.q.queue); // THIS HAS FOO

This is fixed if I instead do this:

e0.addComponent({
  type: 'UnitBuildQueue',
  key: 'q',
  frameAdded: 10,
  queue: [],  // THE FIX
});

Any thoughts? Did this ever get fixed?
