pouchdb-authentication is not working in a webworker

[hans-helmut]

Copying pouchdb.js (7.2.2), pouchdb.authentication.js (1.1.3) and some code together into a webworker script does not work, PouchDB.logIn() keeps undefined.

I just replaced all "window" with "self" within pouchdb.authentication.js and then it works. In my opinion the root-cause is the following code in src/index.js, but I am not able to build pouchdb.authentication.js for testing.

if (typeof window !== 'undefined' && window.PouchDB) {
  window.PouchDB.plugin(plugin);
}
