Steps to reproduce the problem:
1. Inspect the network tab for any app that uses a service worker 
2. Look at the 'size' column
3. Any request fulfilled by the service worker has '(from:ServiceWorker)' under the 'Size' column

What is the expected behavior?

What went wrong?
Why is the 'size' column the indicator of whether a request was fulfilled by a service worker or not ? A request fulfilled by a service worker could have been fetched from the network as well ( network only , cache-first / cache - else - network ) and not necessarily the cache API. 

The 'size' column should reflect the amount of data that was sent to the browser from sever for parsing.

If you show the actual size for requests fetched from the network at least, I can distinguish between requests fetched from the Cache API and the network .

I can still understand '(from disk cache)' appearing under 'Size' since there's no chance of network being involved , but the same is not true for service workers.Even from cache the size is interesting, eg "how much JS am I sending to the parser ?"

Did this work before? No

This will help provide clarity around requests intercepted by service workers.
