When Spiders are neutral during daytime and you punch them, they wait a second before they attack the player.
I've tested with other neutral mobs and Spiders have by far the slowest and most noticeable response time, whereas Piglins respond immediately when punched.
Hi! I actually was playing alpha 1.2.0 the other day and noticed that they attach much more suddenly than in new versions, so I am able to confirm this issue!
