Given that the commit was attempting to improve the performance, I think the change was unintentional. However, feel free to argue that the current behavior is correct. If so, please treat this ticket as [LTA] (the amount of candidates printed is insane).

FWIW, my math[^1] suggests with current system we'd need 22 more candidates to handle Cool, bringing the total to 52 candidates.

IMO Cool candidates are important to have, perhaps we can de-optimize something that won't have a huge performance hit, while reducing the candidates to saner levels?
