Observed behaviour
If you're a member of a thread and someone else sends a message in it, normally you would expect to to light up the same way a regular channel does, letting you know that a new message was sent, but this is not the case if you have the community muted.
Reproduction steps
1) mute a community
2) create a new thread
3) click off of it
4) have someone else send a message in the thread you created
5) ???
6) the thread stays gray
