New messages move channels from favorite to unread

Description:

As of 3.8.1, favorite channels on the sidebar from the Favorites list to the Unread list when they receive messages. The old behaviour was highlighting the channel name in the Favorites list itself.

Since the favorites list is assumed to be a small one, I find the old behaviour to be preferrable. It makes it easier for the user to prioritise their reading order.

Another option is adding the channel to the Unread list while also keeping it highlighted in the Favorites list.

Steps to reproduce:

1. Create a new channel
2. Star/favorite it
3. Check that it is included in the Favorites sidebar
4. In View Mode, activate the "Unread on top" option
5. With another profile, send a message in the created channel

Expected behavior:

The channel name should be highlighted in the Favorites sidebar for the first profile.

Actual behavior:

The channel gets moved from the Favorites sidebar to the Unread sidebar for the first profile
