Summary
As an entity, despite it's constant, the rotation of a Painting can be tweaked with /data. However, Painting’s rotation always looks as if it resets every time the save is restarted.
Steps to Reproduce
Place a Painting. Notice its rotation with F3 + B or in Spectator Mode.
Run:
/data merge entity @n[type=minecraft:painting] {Rotation:[11f,45f]}. Confirm its Y rotation with/data get entity @n[type=minecraft:painting] Rotation.Save the world and back to main menu. Restart the world.
-> ❌ The pitch of the Painting looks as if it reset to 0, but running/data get entity @n[type=minecraft:painting] Rotationconfirms it is still correct.
