This is mainly intended to be used for client-side resources like img and css in this case.

Since we clear the set we need to do this for updates. We already do for suspensey images.

This is intended to be used by various client side resources where the transfer size is interesting to know how it'll perform in various network conditions. Not intended to be added by the server.
For now it's only added internally by DevTools itself on img/css but I'll add it from Flight Client too in a follow up.
This now shows this as the "transfer size" which is the encoded body size + headers/overhead. Where as the "fileSize" that I add to images is the decoded body size, like what you'd see on disk. This is what Chrome shows so it's less confusing if you compare Network tab and this view.
