Blocks that drop XP do not drop XP when detonated by a TNT minecart

• Description

Blocks that normally drop XP (e.g., ores) detonated by a TNT minecart do not drop XP, which is inconsistent with how regular TNT drops XP when it destroys them.

• Steps to repoduce

Shoot the TNT minecart and TNT around these blocks with a flame bow.

• Expected result

Blocks destroyed by both should drop experience orbs.

• Actual result

Only blocks destroyed by regular TNT drop XP.
