The sculk blocks and ores only drop XP from TNT that was directly lit by the player. This makes automatically farming sculk blocks with TNT impossible. The whole mechanic also becomes sort of pointless, since its potential to replace unintended afk zombie piglin farms was the main reason players were excited about this mechanic.

How to recreate:
1. Blow up naturally generated sculk with TNT lit by flint and steel held by the player
2. Blow up naturally generated sculk using a dispenser filled with TNT

Expected Behaviour:
Sculk blocks are like containers that store xp, so they should drop XP from any Explosion just like a chest drops its items when it blows up
