Over on Aviation, some of our tags aren't showing their excerpts unless you hover on them, for example atc, cvr, united-states. Note that iacc is correct:
Note that this is unrelated to this status-completed bug where the excerpts weren't showing due to showing the main body instead.
The tags in question are all synonyms of other tags; the excerpt is on the target (long) tag (i.e. air-traffic-control), not the synonym.
If I recall correctly, the synonyms don't show the inherited excerpt there to downplay their visual significance in the list, but I'm admittedly not positive I'm not just imagining that reasoning.
