Unread badge not showing up

[jonimettala]

Hey,

Even though I have enabled "unread message badges" from service options, the badge is not showing up. Not for channel messages nor direct messages.

I took a closer look into the recipe and was able to fix direct message and channel message badges by using the following CSS in webview query selector: #SidebarContainer .SidebarChannel.unread

I've just started using Mattermost and I don't know the difference of all the different message types (webview has "team messages" and I have no idea what that is), so I can't do a complete fix PR myself.
