Piglins, brutes and hoglins of the bastions doesn't drop xp when killed

Could you please attach the affected world to your report?

If the size of the world exceeds the file size limit, please upload it on any shareable site like OneDrive and link it here. 

It affects any world that i create but only the mobs that spawn in the bastion, other piglins and hoglins still drop xp correctly

I've also noticed mobs I bastions never drop XP

Though it's not serious problem, it will influence the experience of new Minecraft players who are playing 1.20 in the future, while they find that those mobs won't drop any xp balls at all! So please fix it as soon as possible.

still having this issue in 1.20.30
