The stone_block_slab does not appear in the block ID candidates.

Observed Result

• The stone_block_slab does not appear in the block ID candidates for the fill command, and the smooth stone half block argument cannot be searched.

Expected Result

• Currently I have managed to divert it from another candidate like stone_block_slab2, but please bring back the ID of stone_block_slab and make the candidate for the argument appear!
