Dispensers are firing towards one side depending on the direction.

Dispensers are firing more towards one side. (South facing dispensers fire items west, West firing North, North firing West, and East firing North)

What I expected to happen was...:
Items would be fired in a mostly straight but random-ish manner,

What actually happened was...:
Dispensed items were staying to one side

Steps to Reproduce:
1. Place a dispenser is any direction.
2. Put items in it and power it.
3. watch as items shoot towards one side and not the other.
