Can confirm in 1.18.1. Iron Golems naturally spawned can also suffocate when too close to a block.

Can confirm in 1.18.2. @unknown, that is a different issue and is currently being tracked at MC-189332 🙂

Can confirm in 1.19 and 22w24a.

Hello; please could I request ownership of this ticket? There are some amendments I'd like to add to state the overall problem here as I feel it's not concisely clear. The current reporter has been inactive for over five years as well and I'm willing to refine this ticket and keep it up-to-date. Thanks in advance.

Done.

This issue also affects large salmon when removed from a bucket. Sometimes, they suffocate if placed directly next to a block. Should I create a new ticket for this?
I’ve decided to create a separate ticket (MC-279909) since the behavior of where mobs spawned from buckets spawn differs significantly from spawn eggs.
