Trapdoors won't let light through from a light source

[kalleswe]

Trapdoors do not let light through from a light source behind it, i.e. a glowstone. I.e. a glowstone with oak trap doors on each side does not shine in darkness. This seems to be the same bug that was fixed with the carpets that did not work before.
