Pistons when thrown have their opposite sides not visible

When i throw a piston/sticky piston (press the drop key) while looking at it from underneath, you cannot see the base nor side facing away from you.

What I expected to happen was:
See the whole piston/sticky piston block (all sides) when dropped/thrown

What actually happened was:
From underneath, you could not see the base of the piston/sticky piston block and the sides facing away from you.

Steps to Reproduce:
1. Obtain a Piston/sticky piston block
2. Press the drop key (which ever you specified in your control settings)
3. Watch how the base and the sides furthest away from you does not show
