[1.21.1] Change to clothing layering?

[KrampusKid]

While playing today I noticed that I couldn't see my straw hat through my helmet anymore, and when I tried putting my coronet on I couldn't see it anymore either. Was this an intended change I missed in the patch notes? I'm certain before I could see my helmet and my hat at the same time, and really enjoyed having an armoured crown during the warmer months.

 

I'm playing 100% vanilla, save started in 1.20, all settings are default from then.

I coulda swore it was always like that, armor layer always on top.

Had to look through my screenshots but here's one from three days ago, with my coronet showing through my helmet

There have been some clipping issues lately, but to my knowledge the armor layer is supposed to cover most clothing layers. Accessory slots might be an exception.
