I am building a basic platforming game using ExcaliburJS physics. I enabled physics in the main game and in my Actor elements. This all works according to the example code, with the exception of these physics properties:

 this.body.bounciness //and friction, mass, inertia
 this.body.limitDegreeOfFreedom.push(DegreeOfFreedom.Rotation)

The body does not bounce, and can still rotate around the z axis. The whole class:

export class Mario extends Actor {

    constructor(texture) {
        super({ width: texture.width, height: texture.height }) // collision box size is working
        this.graphics.use(texture.toSprite())
        // enable physics
        this.body.useGravity = true // working
        this.body.collisionType = CollisionType.Active // working
        this.body.bounciness = 0.7 // not working
        this.body.limitDegreeOfFreedom.push(DegreeOfFreedom.Rotation) // not working

        // all the console logs are working
        console.log(this.body.mass)
        console.log(this.body.inertia)
        console.log(this.body.bounciness)
        console.log(this.body.friction)
        console.log(this.body)
   }
 }

In my game I enable physics with

class Game {
  constructor(){
    Physics.useRealisticPhysics()
    Physics.gravity = new Vector(0, 800)
    this.engine = new Engine()
    // ...
  }
}

How can I add bounciness and limit rotation on the z axis in ExcaliburJS?
