Another bug may also relate to MC-28289 .If a player mine a instant-mining block like grass, the attack cool down will reset but the indicator will not.

I don’t know if anyone has reported this.

Can confirm in 1.21.11 Pre-release 3

To fix MC-28289 and MC-272517,

MOJANG may just needs to ADD AN EXTRA REFRESH OF PLAYER’S ATTRIBUTES AND ATTACK COOLDOWN at the same tick if the player switch items.

Can confirm in 1.21.11 Pre-release 2
