When attempting to tame an ocelot with a raw fish, after what seems to be successfully taming it (hearts displayed, ocelot doesn't run away), the "Lion Hunter" achievement does not unlock. However other achievements in the game session have been unlocked, usually with some waiting or exiting the world. But "Lion Hunter" does not unlock in recent and previous attempts before.

• Steps to Reproduce Bug: Hold a raw fish, crouch/sneak towards an ocelot and tame (feed) them.
• Expectation: Ocelot should be tamed with hearts displayed on screen and not running away. Achievement gets unlocked.
• What Actually Happens: Hearts are displayed after taming but the "Lion Hunter" achievement is not unlocked.
