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.

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

If any moderator got time and/or tools to do that, that would be awesome 🙂
The length of the list of duplicates goes to show that this (clearly defined and easy to fix) part of the MC-50367 is an actual annoyance to players.
@@unknown, completed.
@unknown Awesome, thank you! 🙂

As of 19w03a, giants no longer have the zombie's AI (or any for that matter), making the baby giant now impossible to spawn.
This is fixed for every other mob, but it still happens with chickens and baby turtles in 1.14 Pre-Release 1.

It still happens to baby drowned in 1.14 pre5
