MC-9553 was mainly fixed, but its duplicate MC-72416 still applies. As asked for in MC-9553, I'm creating a new report for it: Hitboxes render behind Nether portals, even if the entity is in front of it.
Breaking animation is rendered behind water and nether portals
Wrong rendering order of particles, hitboxes, clouds, transparent blocks, breaking animations and various other transparent textures
Hitbox of transparent blocks, such as slime blocks, stained glass or ice, appears behind the block texture
