It is possible to get the death message "[Player] was slain by Shulker Bullet" when being killed by a shulker if it dies before the shulker bullet hits you

It is possible for a shulker to shoot you, but the death message will say it was a shulker bullet. Technically not wrong, but this would be like a skeleteon shooting you and the death message saying you were "shot by Arrow".

I think this is caused by a certain length of time passing between the shulker bullet being shot and it hitting you.

Expected result:

The death message to say "Brevort was slain by Shulker"
The death message "Brevort was slain by Shulker Bullet" to only appear if the projectile did not come from a real Shulker.

Observed result:

The death message said "Brevort was slain by Shulker Bullet"
