In a singleplayer world, if a player receives damage, the damage tilt that was fixed in 1.19.4 doesn't happen, and the old damage tilt happens instead.
Reproduce:
Take Damage
Notice how the Camera tilts to the right
(IT TURNS OUT THIS MAY HAVE BEEN AN ISSUE WITH TEXTURE PACKS (i think, but good to still look into it))
Kinda duplicate of MC-259212.
