[MC-78885] 2 kinds of ID

There is 2 kind of Wooden Slabs. One is the ID 44(metadata 2) and 126(metadata 0). The 44 Wooden Slab, when picked up with Scroll Mouse Button, it comes as Full Block Black and Purple, but the 126 have no problem. In other words, there is 2 Wooden Slabs

Kinda intended. The first one is the original wooden slab. However, it only supported oak. When Mojang added the different wood type slabs, they had to give wood slabs their own block ID, since metadata values are limited to the range 0-15. They never fully removed the old ones though, as that would leave an unused gap in the metadata range that could break some stuff. Also any old maps will still have those blocks rather than replacing them with air.

Tl;dr: They kept the old type to avoid breaking things hugely.
