Describe the bug
For some reason, stone bricks made of Underground Biome stone types have differing mining levels depending on the block form; this behavior is also inconsistant across block types.
To Reproduce
Check the mining levels of the blocks. Stabs and stairs almost always have the Sturdy mining level, all other forms almost always Crude.
Expected behavior
All stone brick block forms of this sort have the same mining level.

Additional context
This is probably due to inconsistencies caused during the mining rework. Similar in scope to #546

Can probably just make it a comment on #546
