      Mobs suffocate when their eye level is inside solid blocks.
      Therefore in cases where the eye height of the mob lies outside of its collision box, the mob doesn't need to be inside a block to take damage from it.

      This can lead to mobs weirdly taking damage or dying.

      Screenshot of affected mobs.

      Ideas to fix this

      1. Manually move the eye position for the hand full of affected mobs (seems what has been done and is reasonable)
      2. Adjust the suffocation rule to only trigger when eye height and collision box are inside blocks
      3. Force the collision box to grow to include the eye height
      4. Force the eye height to snap into the collision box
