Recently I have noticed a bug in the Network tab of the dev tools. Any pending http requests do not show up in the list. Once a pending request has completed successfully, it appears it the network tab. Additionally, 301 or 302 redirects do not show up. I'm on the Chrome beta channel, (currently 63). I don't know if regular version is affected, but the bug has been around for several versions for me. Is there a bug report somewhere for this that I can follow? So far, I have not been able to find one.
