Does not Finish block breaking when new one appears - sel set air

## Some information
Operating system:
Java version:
Minecraft version: 1.16.4 - Fabritone - don't hate me, I am pretty sure this is an overall version-independent problem.
Baritone version: 1.6.1

## How to reproduce
I came across this problem, when using //sel set bedrock. Baritone mines one block, mines the next one, and when a prior one regenerates, baritone switches back, instead of finishing to mine the current block

## Modified settings
BlockReachDistance (to not trigger any anticheats for reach, I think vanilla reach is 3 🤔 )
blocksToAvoidBreaking Bedrock
disableAutoTool

## Final checklist
- [x] Yes
