repro:

1. open devtools network panel
2. load https://www.paulirish.com/2006/think-you-can-recycle-the-single-serving-coffee-packets-think-again/
3. Look at the failed requests  (filter of `status-code:0` works)
4. Try to understand why the failed. All you can see is red text and (failed) as the Status.


However the protocol actually did report additional failure information within errorText. I think we should report this in the UI. Probably within Preview & Response.
