The bug

Sculk sensors do not detect using an axe to clear the wax/weathering of a copper block.

How to reproduce

1. Place any type of waxed or weathered copper block
2. Place a sculk sensor:

   /setblock ~ ~ ~ sculk_sensor

3. Use an axe to scrape the wax/oxidation off of the copper
   The sculk sensor does not detect this

Expected results

The sculk sensor would detect scraping the wax or oxidation off of the copper block.
