Cannot use interactive blocks on creative mode.

I cannot use interactive blocks (chests, crafting table, enchantment table, furnace, stonecutter, brewing stand, anvil) on creative mode. I read on the Minecraft PE wiki that in 0.12.1 you would be able to use interactive blocks on creative, but nothing happens when I tap on the block. (Oh and I'm not sure what my device is, all I know is it's a Lenovo tablet, and yes, I am using 0.12.1 full release, there just isn't an 0.12.1 version id).

What I expected: Chests and other interactive blocks can be used on creative.
What happened: The characters arm just moves and the block lights up. Nothing opens up (like an enchantment table screen).
How to reproduce:
1. Create a world.
2. Make it creative if it isn't already.
3. Put down a chest or any other interactive blocks.
4. Tap on the block.
5. Wait for nothing to happen.
