max-top-level-suites not being triggered for mocha/recommended plugin

[shawnshuang]

It's mentioned in the rules markdown that max-top-level-suites is included in the mocha/recommended plugin.

However, I'm not able to trigger the rule with the following simple test:

import * as assert from 'assert';

describe('Array.length', function () {
  it('should return the correct length of the array', function () {
    assert.equal([1, 2, 3].length, 3);
  });
});

describe('Array.indexOf()', function () {
  it('should return -1 when the value is not present', function () {
    assert.equal([1, 2, 3].indexOf(4), -1);
  });
});

What seems weird to me is that I am able to trigger the other rules (e.g. no-global-tests, no-identical-title).
