Observed behaviour

When using a dispenser to cast a scroll of Channel Power on the player, the scroll is not cast and instead given to the player (just as a dispenser normally gives items).

Expected behaviour

I expected the dispenser to cast the Channel Power spell. In single player, this would be the only way to use the spell.

Steps to reproduce

1. Join a Server
2. Place the scroll of Channel Power spell into the dispenser with a lever to activate it
3. Stand in front of the dispenser and activate it with the lever
4. Observe the scroll appearing in your inventory rather than the spell being cast.
