Image cache issue in service worker with hero banner

[humphd]

We recently added a feature to download a tiny image in the landing page, stretch and blur it, then replace it with a full-sized image once it fully loads. It works great...most of the time.

About 1 in 10 times I load it, it gets stuck on loading the full-sized image, seemingly in our Service Worker cache:

We might need to tweak something with our image caching in the service worker?

This is interesting, I think it also happens on production once in a while too. I haven't been able to reproduce this.

I've seen a few random bugs related to what looks like our service worker. Hard to replicate.
