Inconsistency: Dispensers are unable to deploy boats outside of water, unlike players

Dispensers are unable to deploy boats outside of water, unlike players. This is inconsistent.

Steps to reproduce

1. Set up a dispenser containing boats
2. Activate it
3. Position water beneath the block where the boat would land
4. Activate it again

Observation: In the absence of water, the dispenser drops the boat, whereas players can place the boat without issue,
Expectation: The dispenser should have the capability to place boats outside of water, akin to players' ability.
