The proxy gathered _client_to_upstream and _upstream_to_client with return_exceptions=True. When upstream sends a graceful CLOSE, _upstream_to_client returns but gather keeps waiting on _client_to_upstream, which is blocked in ws.receive() until the browser disconnects. The handler stays pending and the finally: session.close() cleanup is deferred, leaking a ClientSession and an open browser socket. Use asyncio.wait(return_when=FIRST_COMPLETED) and cancel the pending sibling, so the proxy unwinds as soon as either direction finishes. The pumps' bare except Exception already lets CancelledError (a BaseException) propagate, so cancellation is clean and they need no change.
