bug: webfig vs. winbox sniffer

When using winbox to sniff traffic, after starting and stopping sniffer I am able to view the source and destination ports in any traffic. If I start and stop again a second or third time, each time I am able to see source and destination traffic to different URLs.

This appears broken in webfig: only the first time I start and stop sniffer in webfig will I be able to see the src and destination traffic. If I start and stop again going to different URLs., the source and destination columns are empty. If I, however, reboot the router, I can run it again and see the data collected between start and stop.

I don’t have to reboot router to see the data between start and stop attempts in winbox.
