Pillager captain doesn't drop ominous bottle when killed by a tamed wolf

Can confirm, affects 1.21.51. This is a parity issue, as they will drop both items on Java if killed by a tamed wolf. However, from my tests, they will drop the banner if they're killed by a wolf, just not the ominous potion.

Steps to reproduce:

1. Summon a wolf and tame it.

2. Summon a pillager captain using the following command: /summon pillager ~ ~ ~ ~ ~ minecraft:spawn_as_illager_captain

3. Hit the pillager once so that the wolf attacks and kills it.

4. Repeat steps 2 and 3.

Observed results:
The pillager captain will drop the banner, but never drop the ominous potion. If the player kills the captain, it will drop the ominous bottle.

Expected results:
Both the banner and bottle should drop.
