When a new direct message arrives, I see that red-circle indicator on each of the team's tabs. Then I have to go into each of the teams and click on the direct message to make that indicator disappear.
Steps to reproduce
I'm on a Mac. El Capitan OS.
Mattermost version 3.4.1
When receiving a new direct message, open the app window to see a red indicator on each of the team tabs. Then go to one of the team tabs and select the user from which the message is received to see their message, and only then does the indicator for the team you are on disappears. To remove the indicators on the other team tabs you need to select each tab and select the user from which message is received.
When a new DM is received either only active team window displays an indicator or only the team tabs to which sender belongs. More importantly, when I select the sender's name on the left nav to expose his/her message, regardless of which team I'm on, the indicators in all team tabs should disappear simultaneously.
