Chrome Network Request does not show Cookies tab, some request headers, Copy as cURL is broken

I filed a bug report on the chromium project, and got an answer to disable ~~chrome://flags/#site-isolation-trial-opt-out~~ and chrome://flags/#network-service.

However, ~~chrome://flags/#site-isolation-trial-opt-out~~ may affect things such as vulnerability to Spectre-like attacks. So I did not disable it.

I did disable chrome://flags/#network-service and now it works properly.
