Copper Blocks do not respond to axe

Copper Blocks do not respond to using an Axe on them in Java edition 1.21.1.

What I expected to happen was...:
Using (right-clicking with) an Axe should have removed a layer of oxidation or a layer of wax (if present). I have attempted this in both survival and creative mode, using both stone and iron axes.  I attempted it with every stage of oxidation of copper bulbs and blocks, both waxed and unwaxed.  None responded at all.

What actually happened was...:
 Instead, nothing happens except off-hand movement.

Steps to Reproduce:
1. Place a weathered copper block.
2. Right click on it with an axe selected.
3. Observe how nothing changes.
