Bogged doesn't retaliate against attacks from other mobs

Steps to Reproduce:

1. Enable the Update 1.21 Experiment;
2. Find or spawn a Bogged;
3. Allow the Bogged to shoot another mob or another mob to shoot the Bogged.

Observed Results:
Mobs hit by the bogged will turn against it and kill it with no pushback, and bogged hit by other mobs will not react at all.

Expected Results:
The bogged will fight back when hit.

Notes: This doesn't apply to iron golems for some reason.
