I recently learned a lot about how opaque requests can affect the navigator.storage API in the browser, as described here: stackoverflow.com/questions/391097...
Among the complications are that the browser can't read the contents of certain responses and automatically books way more storage than needed which can eat into your storage quotas.
I can't seem to find another really helpful Github issue, but I noticed it's always Jeff Posnick answering all of this and I was grateful to read through some of his answers as I sought to learn more about this issue.
I'll have time in the near future to close the loop on this whole issue and write about it more thoroughly.
