Large entities may get stuck spinning on ledges

[sciwhiz12]

Per a sighting on [REDACTED SERVER] 1.21, the following ledge previously had an iron golem spinning around endlessly (until I believe the 'attack mobs' behavior of the iron golem overrode it).

Witnessed as well by @FiniteReality through video (to confirm I'm not crazy), and asked by @marchermans to make this issue report.

Can confirm, you're crazy 😆

(I can also confirm the bug exists)
