TUNNEL means Squid is just shovelling bytes to/from the client and
server. This is how CONNECT transactions always worked, they were just
not logged clearly.

Any problem that is happening in a TUNNEL transaction is a private
matter between the client and server. They are communicating directly
like the proxy is not present.
