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

In an embedded signage application using many nested same domain iframes we we're using frameType to identify the top level frame for post message communications initiated by the service worker. 

We'll move to ports transferred from the client, but we now could no longer check directly check if the client is top level or one of the nested frames directly.
