When building on jungle trees, leaves start disappearing, eventhough the tree trunk is still there. I've already seen this bug on earlier versions, but I now noticed it once more. Is this a feature or just a bug? Because I can't find anything about it on the internet, not even people talking about it being a bug. It is really annoying though, so I will classify it as a bug.

Oh, and also: Placing blocks on leaves is kinda broken. You click, the block is there for a millisecond and then it disappears again. Kind of annoying as well
