Question about QUIC and Reload

Hi everyone!

I have had behaviour where workers while reloading, continue to receive
connection attempts, which is noticeable by the logs indicating that QUIC
Initial (ClientHello) packets have been submitted. When this occurs, the
connection client does not receive any responses until the timeout occurs.

I expected that when the worker entered the "retire" state, it would not
receive the ClientHello. Would this behaviour be expected?
