DOMException: Failed to execute 'transaction' on 'IDBDatabase': The database connection is closing. #48

I get this exception occasionally for the amp.dev serviceworker. I'm not 100% sure how to reproduce this. Loading the page -> clearing cache in DevTools -> reloading a few times sometimes triggers it. 

amp-sw.js:1 Uncaught (in promise) DOMException: Failed to execute 'transaction' on 'IDBDatabase': The database connection is closing.

I've experienced this serveral times (months ago) when testing Workbox in the PWA plugin for WordPress. I think it's a browser issue, where after clearing browser data it sometimes takes IndexDB to become available again. That's just what I assume is going on.
