Husks can't fit in a two-high space (and babies in a one-high space)

The bug

Husks are exactly 2.01875 blocks tall in bedrock edition, instead of the correct 1.95 blocks. Babies are 1.009375 blocks tall instead of 0.975. As a result, they barely can't fit under a two-tall/one-tall doorway, respectively.

How to reproduce

1. Build this kinda thing

2. Stand where the armor stand is
3. Spawn some husks
