Browsers' IndexedDB are shared across domain

I was working on a major refactor for a PWA which basically changed the DB schema by reducing the amount of versions, nothing outstanding. BUT, I didn't change the DB name.

I was puzzled why whenever accessing the previous version I had to delete the data to have the app load correctly, then I realized that despite the PWA being located at different URL paths, both versions were using the same IndexedDB because of the same domain policy.
