Pickaxe does not break stone button faster than hand

Stone buttons are supposed to prefer a pickaxe for breaking, meaning that higher tiers of pickaxe should break stone buttons faster.

Expected result
Stone button should break faster with diamond pickaxe (like PC)

Actual result
Pickaxes take just as long to break stone buttons as any other tool.

This was tested in Minecraft Java and Minecraft Bedrock to verify that the behaviour is a bug/inconsistency.
