How to repro
Service worker can't be registered.
Expected situation
I expect that...
Other information
This is because navigator.serviceWorker.controller is null when sw isn't registered. But supportWebPush() will return false when it's null, which blocks the sw to be registered.
It's improper to check supportWebPush when registering sw, since sw provides many other functions, such as caching.
