	// ReceiverLoop runs the receiver loop. To stop the receiver cancel the context.
	func (r *wsReceiver) ReceiverLoop(ctx context.Context) {
	runContext, cancelFunc := context.WithCancel(ctx)
	out:
	for {
	var message protobufs.ServerToAgent
	if err := r.receiveMessage(&message); err != nil {
	if ctx.Err() == nil && !websocket.IsCloseError(err, websocket.CloseNormalClosure) {
	r.logger.Errorf("Unexpected error while receiving: %v", err)
	}
	break out
	} else {
	r.processor.ProcessReceivedMessage(runContext, &message)
	}
	}
	cancelFunc()
	}

The receiver loop here doesn't stop when the context is cancelled. The break out is reached only when there is an error from receiveMessage.
