Minor bug: cpu, uptime, etc in winbox stops updating 6.0rc9

When I leave winbox open, the the main bar stats (uptime, memory, cpu, etc) stop updating after being connected for a while. Other things like stats in the interface list continue to update. If I click system > resources, the main bar stats start updating again. Also reconnecting with winbox fixes it for a while. I assume this is related to the release of rc9 since I haven’t noticed it with other routers running other releases.

When the bar stopped updating today, I opened the resources window and it didn’t refresh the main bar, nor is the data in the resources window updating automatically. However, every time I close and re-open the resources window, the data displayed is up-to-date, just not continuing to update. It also doesn’t refresh the main bar like it was before. The interfaces window continues to work the whole time. Reconnecting with winbox to that router does get everything working again like before.
