How deep does jasmine allow for the deep nesting describe suite?

I tried to nest them this way, and seem its stopped at the level where describe("When...spec2 child", function () { starts.

I wonder is that's the level of how deep jasmine allow to nest suites? Or is there something I did wrong? Any help will be appreciated. Thanks!

describe("ModelSpec", function () {
  /*Initial Test Properties*/
  var Subject = require('../../lib/jasmine_examples/Model');
  var Data = require('../../lib/jasmine_examples/MockData');
  var input = new Data();
  var model = new Subject(input);//service itself
  var mock = {
    truthy : true,
    falsy : false,
    obj : {},
    arr : [],
    arrOfObj : [ { } ],
    nul : null,
    undef : undefined,
  };
  beforeEach(function () {

  });
  it("Spec 1", function () {
    expect(model).toBeDefined();
  });
  it("Spec 1.2", function () {
    expect(model).toBeDefined();
  });


  describe("When...", function () {
    /*
    You can initiate another set of test properties vars here
    */
    beforeEach(function () {
    });
    it("Spec 2", function () {
      expect(model).toBeDefined();
      describe("When...spec2 child", function () {
        beforeEach(function () {
        });
        it("Spec 2 child", function () {
        });
      });
    });

    it("Spec 3", function () {
      expect(model).toBeDefined();
      expect(input.id).toBeDefined();


    });
  });
