WORLDEDIT-3142 - Reported by Postre.mus

Hey,

Today I tried to teleport with the navigation wand using the left click through the gap in the slabs (see screenshoot). I only got teleportet onto the top of the slabs, instead of behind them. We are currently running Craftbukkit 1.7.5 with WorldEdit 6.0.0-SNAPSHOT (compiled from 06c248e).

As far as I can tell, this is intended behavior.
