PouchDB sync issue

create.js

var PouchDB = require('pouchdb');

var local = new PouchDB('./db');

function createDB () {
  var promise = Promise.resolve();
  var docs = [];

  for (var i=0; i<100; i++) {
    docs.push({
      _id: 'note/' + i,
      data: i
    });
  }

  docs.forEach(function (doc) {
    promise = promise.then(function () {
      return local.put(doc);
    })
    .then((result) => {
      doc._rev = result.rev;
      doc.revision = 2;
      return local.put(doc);
    });
  });
  promise.then(function () {
    console.log('saved');
  });
}

createDB();

sync.js

var PouchDB = require('pouchdb');
var util = require('util');
PouchDB.plugin(require('pouchdb-find'));

var local = new PouchDB('./db');

function syncDB () {

  var remote = new PouchDB('http://localhost:5984/note');

  local.sync(remote, {
    //live: true,
    //retry: true
  }).on('complete', function (status) {
    local.find({
      selector: {
        _id: { $gte: 'note/', $lte: 'note/\uffff' }
      }
    }).then(function (result) {
      console.info('notes:', result.docs.length);
    });

  }).on('error', function (err) {
    // boo, something went wrong!
    console.error('replication failed:', util.inspect(err, { showHidden: true, depth: null, colors: true }));

}

syncDB();

Steps to reproduce:
