Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Please link to this comment in the description

The following is based on a decompiled version of Minecraft 1.9 using MCP 9.24 beta.

The reason for this is that the classes net.minecraft.block.BlockCauldron and net.minecraft.block.BlockCake do not override the method net.minecraft.block.Block.breakBlock(World, BlockPos, IBlockState) to call the method net.minecraft.world.World.updateComparatorOutputLevel(BlockPos, Block).
