When a reply was posted to a thread I posted on, I got the badge mention (as per my configuration) but the channel with the badge mention did not sort to the top.
There is an issue that was observed during the 5.14 dev single but, was believed resolved.
I observed this on Windows desktop client. This occurred on 5.14-rc5. I had not yet clicked the banner to refresh to 5.14.0
1. Log in with two different browsers to two different users
2. Make sure users are on the same team, with at least 2 channels both users are in
3. With user A post to channel 1 and channel 2 (regular messages)
3. With user B switch to whichever channel is higher in the unreads section
4. With user A mention user B in the other channel (the one user A is not viewing)
Observed: The channel with the mention is not sorted to the top
Expected: The channel with the mention is at the top of the unreads section
