client.postMessage browser support

[vardius]

according to the client.postMessage() documentation and presented example, given solution should work, however client never gets worker message on:

• Google Chrome Version 64.0.3282.167 (Official Build) (64-bit), works on:
• Mozilla Firefox Quantum 58.0.2 (64-bit)

Should we use

self.clients.matchAll().then(function (clients){
    clients.forEach(function(client){
        client.postMessage({
            msg: "Hey I just got a fetch from you!",
            url: event.request.url
        });
    });
}); 

instead of

What is the support for Clients.get()? Maybe iterating over clients and finding the one matching our id is a better way of doing this (for now) then getting client by id ?

Would love to hear someones opinion here. Any help appreciated.
