Large hitbox mobs having inconsistent exit position and can suffocate in surrounding blocks depending on some factors

Large hitbox mobs having inconsistent exit position and can suffocate in surrounding blocks depending on entry portal size, exit portal size and blocks around exit portal.

Seemingly bug fix for MC-80032, the collision resolution code introduced in 22w45a to prevent entities from suffocating in walls has inconsistent behavior and mobs end up suffocating when they shouldn't.

Screenshots were taken in 2 different worlds exit portal in both of them in exact replica while entry portal varies. This causes horses, donkeys, ravagers to suffocate in one instance while not in the other one.

 

Horse survives in crimson forest nether but not in lava lake nether.
