Sometimes, wardens can be seen playing its sniffing animation, while not playing its related sound or exhibiting any of its sniffing behaviors. This occurs once the warden has completed a path towards a vibration source and begins idle movement.

Additionally, if the warden notices a distraction between this point and the next time it attempts to sniff a target, it will immediately play the sniffing sound and behavior.

This would appear to be the result of the memory "minecraft:is_sniffing" being inappropriately set when the warden begins its idle movement (note the boss bars in the attached video).

Reproduction Steps:

1. Load up a new creative world
2. Summon a warden
3. Grab a stack of snowballs
4. Switch to survival mode
5. Throw a snowball
6. Examine the warden's behavior as it reaches the source of a vibration
7. Repeat steps 5 and 6 as needed

Expected Result:

The warden should begin idle movement without activating the sniffing animation.

Observed Result:

When the warden begins its idle movement, the sniff animation plays, and the memory "minecraft:is_sniffing" is added to the warden's memory data.
