Typescript: Properties 'limit' and 'skip' do not exist on type Aggregate

Do you want to request a feature or report a bug?
I'd like to report a bug

What is the current behavior?
I updated from Mongoose 5.10.19 with @types/mongoose to 5.11.6 and got a new error from typescript:
error TS2339: Property 'limit' does not exist on type 'Aggregate<any[]>'
on a line like this:
const data = await Model.aggregate(aggregationPipeline).skip(skip).limit(limit);

If the current behavior is a bug, please provide the steps to reproduce.

Compiling the following with typescript should reproduce the issue:

import mongoose from 'mongoose';

mongoose.connect('mongodb://localhost:27017/test', {
  useNewUrlParser: true,
  useCreateIndex: true,
  useUnifiedTopology: true,
});

const personSchema = new mongoose.Schema({name: String})
const personModel = mongoose.model('Person', personSchema);

const doSomething = async () => {
  const data = await personModel.aggregate().skip(10).limit(10);
  console.log(data);
}

doSomething();

What is the expected behavior?
The program should compile as before
