If you have a powered dragon or piglin head before 1.20.2, it will stop animating its mouth or ears after upgrading the world. However, the heads will animate again when they receive a block update.
How to reproduce:
Create a world in 1.20.1
Place a dragon head and a piglin head adjacent to a redstone block
Load the world in the newest version
Observed result: The piglin and dragon heads won’t animate again until they get a block update.
Expected result: The dragon and piglin heads should keep animating in the latest version without requiring a block update.
