Re: [w3c/ServiceWorker] Edge case for use of client.frameType (#1007)

As of this commenting, both Blink and Gecko still provide `client.frameType`. But that attribute is planned to be [deprecated](https://github.com/w3c/ServiceWorker/issues/732) in favor of `windowClient.ancestorOrigins`, which basically captures and returns the client's ancestor origins information in an array. E.g., `.ancestorOrigins` getters returning an empty array means the client is top level. I'm not sure about the exact time line for implementations, but will it work for your use case?
