Dispensers cannot grow weeping vines using bonemeal.
Steps to reproduce:
1. Place a weeping vine on the underside of a block with space underneath.
2. Place a dispenser facing the weeping vine and load it up with bonemeal.
3. Power the dispenser.
The weeping vine does not grow. Bonemeal is consumed and green particles appear.
The weeping vine grows downwards.
Note that manually using bonemeal on a weeping vine works properly.
