The bug happens when a player gets fire tick damage (e.g. from walking into lava), and then die from this damage causing a respawn. They are still applied damage after the respawn delay.

Expected result:
Player should die from fire tick damage, then remove it.

Actual result:
Player dies from fire tick damage, then after respawning, catches fire again.

Steps to reproduce:
Step 1: Walk into lava and die from damage
Step 2: Respawn counter is displayed, wait
Step 3: Respawned and you now catch fire again
