Cross-posting from Updates to the site, since it was a bug with that update that appears to have gotten missed. Comments on that answer haven’t seemed to get noticed, so giving this a little more visibility:
Questions with favorited tags are no longer being highlighted.
It's difficult to get a good screenshot of this, but it's easy to check.
I’m still seeing this, and based on the four upvotes on my comment to that effect, so are others. This is despite the status-completed entry on the answer, suggesting that it would be live after the next build (all other fixes marked the same have been visible for several days).
