If you place many slab and go in a mincart under the slab, you see through the slab
WARNING : IT'S NOT THE SAME BUG THAT MC-1769 WE ONLY SEE THROUGH THE SLAB
WARNING 2 : IT'S NOT A DUPLICATION OF MC-134722 AND MC-134200, THIS BUG WAS FLAGGED RESOLVED WRONGLY
MC-134200 Slab XRay
Still works in 1.15.1 prerelease 1.
But the slab is a solid block and we shouldn't see through solid block, included slab
i think this is expected behavior, as slabs are transparent blocks (just like leaves, glass, stairs, etc.).
Still works in 1.15.1 prerelease 1.
