The player's ability to interact with mobs through corners is inconsistent

The player’s ability to interact with mobs through corners is inconsistent. Specifically, a mob can push the player (or another mob) through a corner, but depending on the player’s viewing angle, they may not be able to punch or right-click said mob.

To reproduce:

1. /setblock ~1 ~ ~1 stone

2. /setblock ~1 ~1 ~ minecraft:oak_shelf[facing=north]

3. /setblock ~ ~1 ~1 minecraft:oak_shelf[facing=west]

4. Enable hitbox rendering with F3+B

5. /execute align xyz run summon minecraft:chicken ~1.2 ~1 ~1.2 {NoAI:1b}
   The chicken is right up against the shelves, as much as would naturally be possible

6. Walk into the corner
   Note how the chicken pushes you back when you release W

7. Switch to survival, and switch to your fist

8. /execute align xyz run teleport @s ~0.5 ~ ~0.5 -45 20

9. Left-click
   You do not hit the chicken, and instead begin breaking the shelf

10. /execute align xyz run teleport @s ~0.5 ~ ~0.5 -45 15

11. Left-click
    You succeed in punching the chicken

Expected behavior

The player’s ability to punch or right-click a mob pressed up against a corner should be consistent with itself and with the player’s ability to collide with said mob.
