We've had numerous issues in PouchDB due to subtle differences between Webpack and Browserify:
- apache/pouchdb#3647
- apache/pouchdb#3319
- apache/pouchdb#3287
- apache/pouchdb#3787
- apache/pouchdb#4700
- apache/pouchdb#4709
To deal with this, we've started testing Webpack separately in CI (apache/pouchdb#4701),
and we're probably going to start shipping one single index.js bundle to avoid end-user problems (apache/pouchdb#4652).
