ServiceWorkers in Hub and Keyguard are blocking each other

I was able to create an account and go past this screen on the testing iPhone without problem.

And now I experience it, too... :(

The issue has been traced back to the service workers on the Hub and Keyguard origins, which when both active, for some unknown reason block each other on iOS Safari. Safari on Desktop does not show this issue, although the service workers are also enabled there.

This looks like an iOS bug, which cannot be further tracked down.

For now we have heavy-heartedly disabled the service worker in the Keyguard, as that cookie contains less critical information (only the keyId, and the type of key), whereas the Hub cookie contains all active addresses and labels as well.
