TNT Explosion Sounds Cannot Be Heard/Particles Cannot Be Seen On Death Screen

When you die as a TNT goes off, you can't see or hear the explosion; nor can you see the blocks being destroyed by the explosion until after you respawn.
In 20w06a, the explosion actually doesn't go off (at least in singleplayer). It saves the explosion, and the TNT eventually explodes only until you respawn again, strangely.
