MCPE-21413Slab Transparency bug
I WOULD LIKE TO REQUEST THAT MY ISSUE IS TO BE REOPENED
So recently I have started building a mob farm designed by Snocrash. This farm works off of normal game mechanics, being that mobs will spawn in low light levels within a certain distance from the player. This farm consists of me building a giant donut-shaped platform at Y=255 using blocks that block mobs spawning on top of them, and block out light. Here is when I noticed that while building my spawning platforms that nothing was spawning because light was coming through the slabs. This bug means that if I were to block myself into a hole and place a slab on top of me, all light will still come through.
I believe this bug also affects stairs as well.
UPDATE!
After one of the mods told me that this is considered normal behavior I knew that wasn't true, in a video by Xisumavoid where he tested which blocks could be placed above a beacon beam, he found that all blocks that are considered "Opaque" (being that, for example, a zombie could stand under and not burn during daylight), and slabs and stairs were under that. I have decided to test this myself and found that even under slabs a zombie will still burn during daylight. I also decided to see if a slab would obstruct a Beacon Beam, and it didn't. Furthermore, in Snocrash's video, mobs are clearly spawning under a slab during daylight. While you could argue that this feature is just something that differs from PC to WIn10/Pe, I do not believe that this is something that should differ.

Slab transparency in PE/W10 is considered working as intended, see
MCPE-363Yes, on this version it is considered to be working correctly, but this is limited only to this version. On the official Minecraft wiki is clearly states that "Slabs, stairs, and farmland block light completely (except in Pocket Edition)."
EXCEPT IN POCKET EDITION
This is absolutely no reason as to why this should differ from other versions, as much as WIN10/PE is not meant to be the same as the PC edition.
I almost think that this another change made to prevent players from doing using items to their fullest potential, for e.g cacti doesn't grow if any block would obstruct it, or being able to shoot yourself with your own bow.
