	For sorting topics in the left sidebar topics list, the "Followed" topics are treated the same as "Unmuted" topics. In a muted stream and not zoomed state: * followed/unmuted topics at the top. In an unmuted stream or zoomed state in a muted stream: * normal recency sorting The reason is that the "Followed" topics have a tier of interest above being unmuted, so they shouldn't lie below the "Unmuted" topics in the list.
