[MCPE-141935] Looting is not applied when a mob is killed with a projectile

Please remember to observe the bug tracker guidelines: Comments must provide additional information for the developers only. We also allow you to share a workaround in a comment, because that is generally helpful to the developers.

For those of you who mentioned that loose tridents in the world are disappearing, that is a separate issue and is being tracked as ~~MCPE-141539~~.

Bug
When a mob gets killed by a projectile, the loot from the mob will not be applied with looting, resulting in less drops from the killed mob. This happend after the 1.17.30 update

Expected result
The loot from the mob gets applied with looting. Just like it happens on Java.

Observed result
The mob only drops the amount of loot that is the same as killing a mob without looting.

Steps to reproduce
Step 1: Shoot an arrow or trident against a Ghast with 1 or 2 health left (try punching the ghast 3 times before shooting)
Step 2: Switch as quick as possible to a looting 3 sword in your hand
Step 3: Look at what the Ghast drops, only 0-2 gunpowder and 0-1 ghast tears. This should be 0-5 gunpowder and 0-4 ghast tears per Ghast

Media
I have added Looting test 1.17.10.mp4, Looting test 1.17.40.21 beta.mp4 and Looting test Java.mp4 to the bugreport.

In 1.17.10, using a trident, the ghast drops:
-With trident:
3 gunpowder and 1 ghast tear. Because I got 3 gunpowder, means there must be looting applied as getting 3 gunpowder is impossible without looting (max loot of gunpowder without looting is 2 gunpowder
-With bow:
3 gunpowder and 4 ghast tears. The multiple ghast tears shows that looting is definitely applied in 1.17.10 on mobs killed by looting

In 1.17.30+ (the recording is done in 1.17.40.21, but 1.17.30 experience the same issue as seen by the other attachments)
-With trident:
1 gunpowder. Because I got only 1 gunpowder, it can be said looting is not applied
-With bow:
1 gunpowder and 1 ghast tears. This once again shows looting is not applied if mobs are killed by projectiles

In Java you can see, after throwing the trident, it will drop the loot with looting applied. This means the change in 1.17.30 is in disparity with Java
