  Backend developers say that server closes the connection on %some_event% but as far as I can see in the inspector it's still open.
  Does 'pending' label in the inspector mean that it is open?
  If server sends readyState === 3 (CLOSED) can we see the frame with smth like 'CLOSED' text and reason in frames tab?</p>
  
  <p>In other words how can I inspect the event: 'server closes connection' in DevTools?</p>
