player wearing netherite armour doesn't take damage by tnt explosions

in my survival world, I i was wearing full netherite armour at the time, with protection IV with it. I happened to stand in the TNT once I lit it and it yelided no damage. This bug makes TNT harmless no matter how much TNT is blown right next to the player.

how to replicate:

1. wear full netherite armour
2. place TNT and light it
3. stand close by where in range of explosion damage

 

NOTE: The TNT still pushes the player back like it should
