navigator.serviceWorker.register error on console

WKWebView: navigator.serviceWorker.register method fails for a new version of an already registered service worker.

Overview

    The issue here is that it is not possible to use register method to load a new version of service worker once 3 registrations are reached.
    In this case the register operation does not violate the limit as its an update operation.

Steps to Reproduce

    1. On WKWebView try to load 2 websites with service workers
    2. From a new website execute -> navigator.serviceWorker.register('sw.js?version=1')
    3. Now the max limit of 3 is reached.
    4. After this try to update the service worker by executing -> navigator.serviceWorker.register('sw.js?version=2')

Actual Result

     -  register method fails with the error - "TypeError: Job rejected for non app-bound domain".
        This happens even though the limit of 3 will not be exceeded.

Expected Result

     - register method should not fail if the limit of 3 is not exceeded.

Environment

    Device: iPad Mini 4
    OS: iOS 15.0 (19A5325f)
