Bonemeal Acacia and Dark Oak Saplings

When trying to grow Acacia and Dark Oak saplings near 2 high grass using bonemeal it won't grow.

What I expected to happen was...:
Sapling will grow normally.

What actually happened was...:
No matter how many bonemeal I use tree won't grow.

Steps to Reproduce:
1. Plant Acacia Sapling (or 4 Dark Oak saplings).
2. Use bonemeal on grass next to sapling to make it 2 high (bug also occurs with 2 high grass generated by game).
3. Try to grow sapling with bonemeal.
