[MC-266796] Mobs NoAI with Set Rotation Sometimes Lose their Rotation Upon Relogging

I have attatched a clip of the issue happening. While this clip is shown in the latest snapshot, I had the same issue with a ghast in 1.20.1.

(Please ignore all the redstone block item displays, they are for a custom boss fight I am working on, which is a heavy work in progress)

Please provide steps to reproduce in a minimal test setup. Make sure no command blocks/data packs might be modifying the rotation when you leave/re-enter.

@Dhranios The setup can be reproduced in vanilla. All you need to do is summon an entity: a ghast, a wither, or probably other mobs that have not been tested, with the NoAI and Rotation tags. So, the command would be: /summon minecraft:ghast ~ ~ ~ {NoAI:1b,Rotation:[90f,0f]} I have attatched a video of those steps being reproduced in a newly created flat world. I was unable to produce the exact same result, however, if you look closely you will see the wither turn its head slightly upon logging in. I am unsure if this is related.

I'm unable to reproduce this. Please can you see if this is still an issue in the latest snapshot and release?
