What I expected to happen

was for the shadow of magma blocks to behave like the shadow of a normal solid block.

What actually happened

Magma blocks casted a shadow that affected the light level too much.

Steps to reproduce

1. Make sure smooth lighting is turned on
2. *Place magma blocks near a light source 
3. Notice the difference between the shadow of a magma block and a solid block.**

Although not required, I noticed that this bug is even clearer when magma blocks are arranged diagonally/ in a checkerboard pattern.*

Additional Notes:

This bug does not seem to occur when smooth lighting is turned off.
