Required damage doesn't work for drops

Summary

I have FancyDrops with RequiredDamagePercent:5 but any player that made a hit gets the drop.

Steps to reproduce

Drops:
  - EndWalkerDropTable 1
DropOptions:
    DropMethod: FANCY
    ShowDeathChatMessage: false
    ShowDeathHologram: true
    PerPlayerDrops: true
    ClientSideDrops: true
    Lootsplosion: false
    HologramItemNames: false
    ItemGlowByDefault: true
    RequiredDamagePercent: 5
Modules:
    ThreatTable: true

In a droptable I have MythicItems, only 1 of them must be dropped.

EndWalkerDropTable:
  TotalItems: 1
  Drops:
  - NightmareBow 1
  - HealingSword 1

Current behavior

Any player that dealed at least 1 hit can get the drop from the mob.

Intended correct behavior

Should work as per percentage of damage by player.
