While farming bamboo in my world, I observed that some of the bamboo were growing very tall. So, I tried to place 2 stacks of bamboo manually on grass. It should have stopped at around 16 blocks, but I was able to place all of it. I tried the same in another world in creative mode and the same happened.

Steps to Reproduce:

1. Open a Creative world
2. Obtain bamboo
3. Place the bamboo by holding right click

Observed Results:
Bamboo stops being placed when the bamboo stalk reaches the build limit.

Expected Results:
Bamboo should stop being placed when the bamboo stalk is around 16 blocks tall.
