Bug: New item temporarily added to wrong sublist on other devices #65
Description
I'm running the app as hosted at https://ibm-watson-data-lab.github.io/shopping-list-vanillajs-pouchdb/# and connecting to my Cloudant DB, with one Chrome window and one Firefox window running to represent different devices. If I visit a different sublist in one browser than the other and add a new item to it, it appears on the screen I'm currently looking at in the other browser, meaning it puts itself temporarily in the wrong sublist. If I refresh or go back to the list of lists and back in, the issue is resolved and the new item is shown in the right place.
For example, in the screenshot below I added an item to the electronics sublist in Chrome and it appeared immediately in the Groceries sublist on the right.
