Fence gates and trapdoors do not update piston BUDs

Opening/closing fence gates or wooden trapdoors do not update piston BUDs

How to reproduce:

place a sticky piston facing sideways, place a slime block on it's face, place a redstone block on top of the slime block, and place a regular block in line with the sticky piston and the slime block. Now place a trapdoor or a fence gate beside the sticky piston, and close it. The sticky piston will not move when it is closed or opened.
