Clicking on blocks out of reach turns on Bedrock-Miner to break it while Bedrock-Miner does not immediately activate, meaning when you move towards it, Bedrock-Miner suddenly activates.
Walking away does not remove that it will try to break it when you near the clicked block, nor does breaking other bedrock.
The video below shows this happening

Hmm maybe just check where it is, and make it more api line and do it to the list as normal
