[MC-2320] Mushrooms generate in leaves

When I generated a new world, (seed 2391353702220912231), I noticed some mushrooms in jungle leaves in coordinates X 291 Y 81 Z 343. Mushrooms shouldn't generate in any type of leaves, as they aren't placeable in anything that's not dirt.

That actually looks awesome and realistic for jungle biomes, in my humble opinion. I'd rather allow mushrooms to be placed on leaves than removing this feature. But that's such a minor thing that I would close this issue so mojang can concentrate on more relevant issues.

Mushrooms spread everywhere, not only on dirt blocks. In my house I have mushrooms on chests. This is not a bug.

This doesn't work as intended since they pop up when they receive a block update, showing that they are in an invalid state. World generation shouldn't generate blocks in invalid states.
