+Fixed a UI issue that allowed a user to "mark" a room as favorite even when a room was not default. The Back-End was correctly ignoring the `favorite` property from being updated when the room was not default, but the UI still allowed users to try.
+As UI allowed but changes were not saved, this gave the impression that the function was not working.
