I added jQuery a little while ago to my favorite tags, and since then it has never highlighted the posts with jQuery as a tag. Is this a bug, or am I missing something.
If you're in a favorite tag, searching for it specifically, we purposefully do not highlight. Highlighting is intended to, ya know, highlight things among others, showing which ones are special.
If all questions are highlighted it really doesn't make any sense, so we don't do it, this is status-bydesign
