Sniffers continue digging after being pushed or pulled away from their target block

The Bug:

Sniffers continue digging after being pushed or pulled away from their target block.

As a result, sniffers start digging blocks that they weren't originally going to dig. They will only stop digging once pushed/pulled onto a block that isn't part of the "#minecraft:sniffer_diggable_block" block tag. Making sniffers unable to be pushed or pulled while digging (MC-260245) would be the ideal way of fixing this problem.

Steps to Reproduce:

1. Obtain a lead, summon a sniffer, and wait for it to begin digging.
2. Once it begins digging, use the lead to pull away the sniffer from its target block.
3. Observe the behavior of the sniffer.
4. Take note as to whether or not sniffers continue digging after being pushed or pulled away from their target block.

Observed Behavior:

Sniffers continue digging after being pushed or pulled away from their target block.

Expected Behavior:

Sniffers would stop digging after being pushed or pulled away from their target block.
