Describe the Bug
Observed behavior
The Network > [specific request] > Response tab in DevTools shows a message stating "This request has no response data available":
This happens when the response is large, I haven't managed to pinpoint exactly when it starts happening.
Expected behavior
The Response tab to show the response that was received in the worker.
Reproduction
// found this publicly available JSON endpoint that is large enough to reproduce this behavior
const json = await fetch('https://jsonplaceholder.typicode.com/photos');
I've transferred this to the workerd repo, since I think this is a runtime bug. See the playground for a reproduction, but essentially it looks like cfResponse is empty on CDP Network.loadingFinished events when the body is too large. @irvinebroque would someone be able to take a look at this?
