Skeleton Horse Traps still trigger when in the death animation

The Bug

I was messing around with the skeleton horse trap and I found out even if I kill the initial skeleton horse, it will still generate even if I get close to it while still in its death state.

Reproduce

• Do /summon skeleton_horse ~10 ~10 ~10 {SkeletonTrap:1}
• Get a Bow and Arrow
• Shoot the summoned Skeleton Horse
• When it dies move towards it

Observed Result

The Skeleton trap still spawned

Expected Result

The Skeleton trap wouldn't spawn
