Ghasts Killed by Deflected Fireball Explosions Do Not Drop Music Discs

Description:
In Minecraft, when a ghast is killed by a player-deflected ghast fireball, it should consistently drop a music disc regardless of whether the death was caused by:

1. Direct impact (fireball directly hits the ghast), or

2. Explosion damage (fireball explodes near the ghast)

Currently, only direct kills result in music disc drops, while explosion kills do not. This inconsistency contradicts the intended mechanic.

How to Reproduce:

1. Deflect a ghast's fireball back at it

2. Observe drop results in two scenarios:

   • Direct hit: Music disc drops (correct)

   • Explosion kill: No music disc drops (incorrect)

Observed Result:

• Music discs only drop from direct fireball impacts

• No music discs drop from explosion kills caused by deflected fireballs

Expected Result:
Both direct kills and explosion kills should produce a music disc, as the player's action (deflecting the fireball) is the cause of death.

Technical Background:
This issue stems from loot table conditions not properly handling explosive damage sources. Specifically:

• Fireball explosion damage fails to trigger loot drops

• The same behavior would affect other explosive-based mob deaths (e.g., if similar conditions were applied to creeper loot tables)

• Indicates a systemic issue with how explosion damage interacts with loot table conditions

Additional Notes:
This affects gameplay consistency and the reliability of music disc farming methods. The behavior should be unified to match the intended mechanic where any player-deflected fireball kill (direct or explosive) drops a music disc.
