Item that deal damage more than teammate HP can kill teammate

[MastaMiki]

Description

When in dungeon default configuration set friendly fire to false right? (if not true, I set friendly fire to false in configuration for sure) but with item that deal damage more than teammate HP can kill teammate and losing lives

Reproduce

1. just join group with some player
2. play some standard setting dungeon ([ready] sign, [lobby] sign, [end] sign, [start] sign)
3. hit teammate with some item that deal damage over teammate HP (In this case i use iron sword with sharpness 60)

Expected behavior

teammate should not die but he's die and losing lives
