I found a bug that the particle did not disappear even if I did True when granting the shock absorption effect.
Reproduction procedure:
Reproduction procedure: 1: Enter the world where the cheat is on, 2: Enter "effect @p absorption infinite 1 true" in the chat field or command block.
Expected result: The particle does not disappear.
Actual result: Particles disappear.
Does the issue still occur if you disable your resource pack?
