Bug Description

We apply a negative amplifier health boost effect in certain gameplay situations. When applying this, we have found that 1.7.10 players are prompted with a death respawn screen in which selecting respawn does nothing.

This screen has showed in select alternate situations however I have not been able to find other reproducers.

Steps to Reproduce

1. Log on with a 1.7.10 client on a 1.8.8 server
2. Apply a health boost effect with a negative amplifier (need separate plugin from vanilla)
3. Potentially observe non-functional respawn screen

Expected Behavior

The negative amplifier health boost effect should not trigger the respawn screen.
